Jim Carter Truck Parts

Almost unchanged in 45 years! The second owner repainted the two doors to cover the town lettering, then added the "Moblegas" decals. Yes, the hubcaps, bumpers, and grill back splash bars are still the correct gray color due to 1953 Korean War shortages.

Wow! Now this is a real work truck. Used almost daily, it was bought from the original owner in 1985. This 1967 Chevrolet 1 ½ ton is a true heavy hauler. It's original 283 V-8, 4 speed transmission, single speed rear end, and high output heater remains in place.

Our 1942 1 1/2 ton Chevrolet Fire Truck Was delivered to the DeLand Naval Air Station, February, 1942.

  Strange but true, 305 V-6 valve covers on 1963 GMC 1/2 ton pickups came with a red, yellow, and black plaid design. The red color was used on the remainder of the engine without the yellow and black markings. These photos are of an original untouched V-6 GMC engine. At this time, we are unsure why GMC used this...

  Chevrolet's 1/2 ton and car 3 speed overdrive transmission was optional equipment installed on the assembly line during the 1950's. The reduction of engine RPM's in high gear resulted in less wear on the drive train as well as additional speed on level roads. Today, this is still important but of increased importance is better fuel economy. The standard...

This drawing is from the 1955-1959 Chevrolet Factory Assembly Manual. We have added our part number ( FL137 ) with an arrow to show the new floor shift foam collar that is now available at Jim Carter's Truck Parts. Click to enlarge

  It's the first year for the successful Chevrolet V-8. (This basic small block design continues even today over 50 years later.) One very unique characteristic of this first year V-8 is the lack of a traditional block connection for a positive flow oil filter. For this one year, this 265 engine carried the by-pass oil filter system much like...

  Chevrolet linkage-type power steering is now available optionally on Series C10, 20, 30 models. This was formerly a dealer installed item. The equipment consists of a hydraulic pump, power cylinder, control valve, relay rod and hoses. The power cylinder is mounted to the side of the engine and is connected to the control valve through the hoses. The control...

  By 1958 the Chevrolet V-8 fan shroud (not GMC) changed to the more traditional round design. During the V-8 beginning years in 1955-1957, it was little more than four pieces of custom sheet metal that helped pull air through the radiator core. The enclosed pictures are of an original fan shroud for a 1958-59 Chevrolet 283 V-8. It fits...

  Two totally different 12 volt starters were used on the 235 six cylinder Chevrolet light trucks during 1955-1959. They attach to different bellhousings and are not interchangeable. Hydromatic 3 Bolt Starter As shown in the photos, the Hydramatic transmission starter has three bolt holes for securing it to the bellhousing. A solenoid on top reacts to the drivers key...

  Chevrolet's linkage-type power steering is available as an RPO (Regular Production Option) on all models except Forward Control Chassis. New ease and fingertip steering control are provided because up to 80 percent of the steering work is done by hydraulic power. Maneuvering a heavily loaded truck in a small space becomes much easier, and straightaway highway travel is less...

  With the introduction of the new small block V-8's in 1955 Chevrolet trucks, modified sheet metal was created to help in cooling. The new truck design came standard with the proven 235 inline six cylinder but when an optional V-8 was added, cooling modifications were necessary. The short length V-8's cooling fan was too far from the radiator and...

Just imagine a truck designed strictly for work duties that has survived almost 70 years! In 1936, our country was still feeling the effects of the "Great Depression". When you spent your money for a 1 1/2 ton truck, it had to pay it's way. Therefore, few big trucks like this 1936 have survived. They were worked from the first day of delivery!

What a rare panel truck! This little 1934 Chevrolet is almost a "one of a kind". With it being under construction, we just had to share these pictures.

Have you ever crawled under a pickup for sale looking for damage? You then turned it down because some rust was coming through the floor. Well, check this! David Cross of Stillwater, Minnesota found this 1957 Chevrolet 1/2 ton and ignored the signs of major rust. What is now a show quality truck would normally have been crushed by a recycler.

  We often get requests for a formula to make the Advance Design pickups more freeway friendly. Their original ring and pinion gears were created to make the truck's six cylinder work well with a load and also keep up with the 1950's traffic on gravel roads and two lane paved highways. Though a higher speed reproduction ring and pinion...

This mid-Missouri 1937 Chevrolet 1/2 ton is owned by Tim Koch of Jefferson City. He chose this restoration shop to do the total project because of their reputation for quality as one of the best! The name Herrons Customs Paint is mentioned at so many local shows, it was worth Tim Koch talking to the owner and viewing his shop. The vehicles under rebuilding convinced Tim this was the company to do the restoration of his 1937 Chevy truck.

</a > On the new 216 six cylinder engine, introduced in 1937, the vacuum advance was placed on Chevrolet trucks and cars at the right side of the engine below the distributor. A small metal vacuum line across the front of the engine connected to the carburetor base. This vacuum advance design continued on trucks through the end of this...

Here is a great example of a ground up restoration of a 1951 Chevrolet 3/4 ton. The project is being done by Line Creek Restorations in Northmoor, Missouri near Kansas City, 1-816-946-6000. When the project is finished, it will be a new truck!

The Trials and Tribulations of Installing a GMC 302 engine into a 1950 3/4 ton Chevrolet Pick Up by Joel Baumbaugh   Background: About 5 years ago I "upgraded" the engine in my truck from a 216 to a 235. Lately I have felt that I wanted/needed a little more torque (especially while the bed is full of something heavy...

This is my latest project a 1937 GMC 1/2 ton pickup. Not exactly original but a personal preference. The previous owner had owned the truck for over 30 years and finally parted with it. It had been restored many years ago but was in need of a lot of repair to shoddy bodywork and I have added many upgrades.

  During the Advance Design Truck years, two air filters were available when an order was sent to the factory. The base air filter (no extra cost) was the oil-wetted design from earlier years. The owner was expected to place a thin layer of motor oil on the filter media. Dirt particles would be caught by the oil as it...

By January 1949 GM realized there was an engine noise in the new late 1947 Advance Design cabs that needed correction. If a truck customer complained, the dealer was given a solution by modifying a part from a Chevrolet car. The problem was engine noise entering the cab through the horizontal accelerator rod where it touched the floor hole. On...

  Between 1954-1962, Chevrolet produced their famous full oil pressure 235 cubic inch six cylinder in trucks and it soon proved to be one of the greats among engines. However, at the same time a lesser known "big brother" to this base engine was being used. This was the quality built 261 cubic inch six cylinder! The 261 was available...

I am glad that you have shown an interest in my pickup. It was purchased from a local theater in 1964 they used it to carry a billboard in the back. After purchase it was used to carry feed and seed on the farm. After purchase of a newer pickup my Dad's employee used it to carry fuel and supplies to a bull dozer until the engine was beginning to fail.

At the beginning years of the 216 engine (1937-1938) the fan blade that cooled the radiator was made with a center hub plus four blades. Each blade was attached to the hub with three rivets. This combination worked well when new, however, it was certainly more expensive to produce. A dangerous part of the design was the blades attached by...

During the 1930's and 1940's most of our Nation’s roads were dirt and gravel. Paving had been underway for many years but there was still a long way to go. To protect engine components from a constant attack of dirt, GM designed metal stamped panels that attached to an area where the engine block and oil pan connect. This slowed...

During the 1936-37-38 years of this cab design, subtle changes occurred as GM engineers learned better ways to construct this truck. The gas tank changes on the pickup body style was probably the most obvious and it was different each of the three years. In 1936, the new mid year low cab pickup continued with the earlier practice of securing...

Though the major cab and fender sheet metal change began in mid -1947 (Advance Design), both the Chevrolet and GMC trucks kept their same proven six cylinder engines as used in prior years. The base engine in GMC light trucks was the 228 cubic inch inline six cylinder introduced in 1939. This overhead valve unit had a full pressure oil system...

Occasionally we hear owners condemning the closed drive shaft system used in the 1/2 ton trucks prior to 1955. After questioning the negative comment, we almost always discover the real criticism is the low gearing of the ring and pinion in the differential. Yes, this lower gear ratio was created more for slower roads of year gone by, but it...

And now we've seen it all! A real example of American ingenuity. Designed by an aftermarket company to keep an over tightened valve cover from leaking motor oil down the engine sides.  A metal band is pushed over and around the base of the valve cover.  Brass U-brackets are then secured by the two valve cover studs.  This creates equal...

Rebuilding the 1937 and older pressure plate can be a little tricky. The early design (activated with a carbon throw out bearing under pressure) requires extra steps when being rebuilt. With the help of an older shop manual (see below) the final details can be successful. The personal letter is from Richard Wright of Westtown, NY. He did not receive...

Chevrolet introduced their basic nine inch single disc clutch and corresponding diaphragm pressure plate in 1938. This pair was used in their cars and most 1/2 ton pickups with three speed transmissions through 1953. With about one million of these vehicles sold annually, one can quickly realize the high numbers of this clutch system that was at one time on...

The door window is cranked up tight in the cloth channel and off you go on your daily errands. Suddenly, the glass begins to slowly lower as you drive over side roads or contact a rough surface. In comes cold air, rain, and wind! Even the window handle turns. What's this all about? Do you tape the window closed or...

Even if you prefer an original vacuum wiper motor for these years rebuildable cores have become very rare and most New Old Stock units are just not obtainable. Even new ones have their lubrication dry after 70 years. For those that won't accept a slow moving or non-working used vacuum unit, an alternative does exist. New electric motors are now...

During the early years of auto and truck design, most vehicles came with their windshields capable of tipping outward. This helped poorly insulated cabs to be more bearable during hot weather. Extra outside air would be forced into the cab and replaced some of the hot air radiating from the bare sheet metal firewall. This idea was good but not...

During 1939-40 Door window breakage on truck cabs became a problem. As the cloth fabric in the door window channel became worn, the large and now loose fitting side windows were susceptible to cracking when the door was slammed. Complaints from dealers resulted in an improvement on 1941-46 doors. A one piece metal frame was placed around the edges of...

  With the introduction of the new Cameo in 1955, GM added their most deluxe features as standard equipment. This "Boulevard Pickup" was to stand out above all others. The wheel covers were not like that on the more standard pickup. To save tooling costs on this limited production model, GM used the wheel cover on the 1955 Chevrolet Belair...

During the early years of GM truck production, many examples exist which relate to their vehicles being designed more for work. Changing a trim part for appearance reasons was usually secondary if it resulted in unnecessary expense. Often parts were used that had already been on GM automobiles. This eliminated expensive new tooling costs and kept GM truck prices in...

Prior to about the mid 1950's, motor oil did not have the modern detergent additive we have today.  Therefore this type engine oil didn't keep dirt particles in suspension. Foreign material would slowly settle to the bottom of the oil pan and on other flat surfaces such as the valley of the head. If you ever removed an oil pan...

Prior to about 1962, Chevrolet trucks were equipped with round straight through mufflers. These units reduced back pressure and allowed the engine to breathe to its full potential. This caused a little extra exhaust noise in comparison to the larger more engineered oval car mufflers but trucks were for work and power. About 1950 truck mufflers were given slightly larger...

  During the 1940's through 1950's placing pin stripes on automobile wheels occurred on most all brands. It was an inexpensive touch that added a little flair to the appearance of a new wheel. The stripe could be added quickly with a machine on a rotating wheel. The factory didn't need a human as on the body stripes. GM was...

The Problem The closed drive shaft ( on GM 1/2 ton, 1937-54) is supported at the front by two bushings. As these wear egg shaped over many miles, the drive shaft begins to move up and down. This ruins the grease seal and causes the u-joint to begin rubbing the "bell" that covers it. Thus noise and vibration! Finally, with...

Before the modern Positive Crankcase Ventilating System (PCV) most automotive engines breathed externally and removed their excess products of combustion into the atmosphere. It was a standard of the industry! The lower end of the engine (below the piston rings) had an attached draft tube that extended outside and below the block. It released blow-by from worn piston rings and...

For Chevrolet Trucks 1929-47, and autos 1929-38. Should last the life of the truck! Remove unit. Remove the four bolts on the transmission tower plate. Knock out the old worn or broken bushing from the tower, install MET136 and add grease. Adding the large replacement tension spring will insure a snug fit. Problem: Slop in the shift pattern on 1947...

The term artillery wheel is a nickname adapted from a scalloped type wheel often seen on US military vehicles in World War I. The similar appearance at a distance to GM's scalloped steel wheels quickly gave them the name artillery. On GM trucks, this style was first used during 1934-36 as a stock six bolt 1/2 ton 17 inch wheel...

About 10 years after the introduction of GMC's new inline six cylinder engine in 1939, General Motors issued a 'Product Service Bulletin' in regards to a recommended improvement on the 228, 248, and 270. It appears the manufacturer discovered a weakness that shortened the life of the engine timing gears. This recommendation was made for enlarging the oil supply hole...

From 1934 to 1959 GM 1/2 tons came from the factory with a tie rod assembly that extended side to side to almost touch the front wheels. With everything stock, the tie rod sits about 3/4 inch from the inside of both original six hole wheels and all fits just right. A problem exists when someone attempts to add a...

If you use a recently manufactured 216 water pump and combine it with the optional larger OEM radiator fan, a slight modification is necessary. The fan rivets will not clear the edge of the pulley hub. You must cut four notches in the hub for rivet clearance. Water pumps in the last five years appear to lack these notches. Note...

Sometimes overlooked by mechanics and restorers is a small vent in the rear axle housing. This part is necessary to keep internal pressure equal to the outside atmosphere. Thus, as the internal temperature of the differential warms during use, any expanding heated air is vented and no pressure occurs. This saves wheel and pinion seals from leaking. Check for this...

What an unusual seat on the 1967-68 Chevy/GMC pickups!  It was standard equipment on the “top of the line” Chevrolet CST and GMC Super Custom pickups. The seat consisted of two bucket seats and a much smaller center cushion referred by many as a Buddy seat.  It allowed for a third passenger or the back cushion could be lowered horizontally...

  GMC Super Custom Interiors offer the ultimate in comfort and style, including plush bucket seats with vinyl covering and matching center seat console. The GMC Super Custom also includes appearance and comfort options from special horn button to carpeted floor.

One series of the famous "drop out" GM differentials was used between 1946 and 1972 on 3/4 and 1 tons. The complete assembly (often called a pumpkin) will interchange during these years with no alteration. The highest gearing in this series is the 4.10 ratio and is found in most 1967-72 3/4 tons with automatic transmissions. Therefore, those "low gear...

  For those not requiring the original seat cushions on their 1955-59 Task Force truck, a roomy comfortable substitute is available. This unit is from a 1988 body style Chevrolet or GMC truck and is almost a bolt-in. The legs or side brackets on this newer seat comes attached to the cushions from a used truck and sets nicely by the...

When you notice your head, tail and dash lights are often dim, sometimes even flicker on a rough road, check your cab to frame ground cable Because the 1967-1972 cab and radiator supports are separated from the frame by rubber mounts. GM used a small mount woven wire ground strap that by-passes one cab mount. This insures electrical flow even...

  Contrary to what almost all Chevrolet truck parts dealers list in their catalogs, the 1969-1972 headlight bezels were not alike. Though today all are reproduced in bright-anodized aluminum. This is actually only correct for 1971-1972. The 1969-1970 bezels were black stamped steel even on the most deluxe models. This color is necessary to blend with the two horizontal black...

  The cargo light above the rear window on the 1969-72 GM cab was a factory option and is mostly seen on the more deluxe trucks. This light is controlled from a switch beside the interior dome light and is wired so it will not operate while the truck is in the forward gear. This prevents the bright 21 cp...

For those on a quest for near unobtainable GM options, this one will provide years of searching. During the mid 1950's, backup lights began to show growing popularity and were occasionally seen on pickup trucks near each rear fender. The limited production 1955-56 Suburban was no exception but the location for its backup light was unusual. Their single center tailgate...

  The differences between these two series of tail lights is an excellent example of lowering costs during production. To keep competitive, manufacturers will always consider making products of equivalent quality, but at lower prices. In 1960-1966, GM, as well as several aftermarket companies, used a redesigned tail light lens and eliminated the need for the earlier metal bezel. The...

The 1955-59 Chevrolet and GMC originally came with a non-metal shield to direct light into the ignition switch to the key slot. This shield is almost always missing after fifty years. Most shrink after twenty years and fall from the switch. The accompanying photos show this snap-in shield in place. Even the die cast opening is notched on all switches...

  The rear fleetside fenders on the 1955 through 1966 are usually considered the same. The reproductions on both metal and fiberglass are listed in catalogs and related advertisements are shown as being identical on the right and identical on the left. Not true! GM modified this last year fender of the 1955-66 series with a stamped indention in 1966...

  To keep vehicles base price low, GM made many items dealer accessories. If the buyer required extras, the dealer was the installer. This created less complications on the assembly line when they were special ordered and added more income for dealerships. One exception is 1966. That year, the US Dept. of Transportation made it a requirement that all cars...

It is sometimes asked by restorers, 'What is the correct fabric for a 1959 Chevrolet with a custom cab?' Answer: The same cloth material was used on the top of the line seats and door panels throughout. The following pictures show this interior material on a 1959 door panel in a 1959 Chevrolet custom cab with 12,000 original miles...

Locating a pair of seat cushions for the 1939-46 truck has become very difficult in recent years. These early trucks increased popularity is the main reason for the shortage. Even when a pair of cushions are located the asking price often does not justify the purchase because of the age damage to the springs and frame of the lower cushion...

With the introduction of the Advance Design panel truck in mid 1947, it was soon evident that a serious safety hazard existed with a few companies, some night deliveries required the rear double doors to be open. This prevented the taillight from being seen! No doubt this caused some accidents particularly with a fast vehicle coming from behind, with dim...

  Beginning in 1951, the rear bumper became an option on both Chevrolet and GMC pickups. This required a change in the standard left tail light bracket. The tail light assembly was now unprotected without the bumper. GM created a new bracket design that brought the tail light slightly ahead of the rear edge of the stake pocket. In this...

  The Chevrolet and GMC left commercial taillight used during 1947-1953 is an excellent example of GM's conservative thinking towards trucks. The number one purpose for trucks was work! Therefore, if a part had been very successful on a prior body design, it just might be adapted later as a part in some new styling. Savings were in production costs...

A redesigned parklight assembly was started with the introduction of the 1947 GMC advanced body style. It was placed in the front fender 3-1/2 inches below the headlight ring. A 2-5/8 inch diameter bezel held a domed glass lens to its housing by two barrel screws. The unit was not meant to be a combination turn signal and parklight assembly...

The introduction of factory sealed beam headlights came to the automotive industry in 1940. It was then necessary to create park light assemblies. (They could no longer be incorporated in the bulb and reflector style headlight as before). To some, the first 1940 GM assemblies were simply "add-ons", maybe a quick design due to the fast industry acceptance of the...

Though items were shared between GMC and Chevrolet trucks between 1936 and 1946, General Motors made sure many parts remained very different during the early years the GMC preferred very few things to be similar to Chevrolet.  Their customers needed to see an almost stand-alone truck with the higher price of the GMC. One very obvious difference is the change in...

  When viewing older GM cars and trucks we see both colors of park light lenses. There seems to be no consistency that gives us the proof of what is actually correct, however, it is easy as remembering a year. Beginning in 1963, the Department of Transportation new regulations required park lights to show an amber color, to be seen...

Jim Carter Truck Parts seat cover kits are produced with an emphasis on originality. The materials are top quality for many years’ service. Seams, ribbing, etc., are based on original seats. We recommend that installation be done by a professional upholstery company. However, if you wish to do it yourself, here are several important steps to follow: 1. Seat springs...

Two major changes occurred in 6 volt General Motors sealed beam bulbs (are actually not sealed beams) since they were first installed on vehicle assembly lines in 1940. The perfectionist restoring his truck to exact original specifications must have the correct headlights for his year. In very competitive judging, it’s these details that can make a difference. No doubt, replacement...

Four Speed Backup Light Switch - They Did Exist! The first design of the 4-speed synchronized truck transmission, introduced in 1948, was used through about 1965. About mid series, when the dealer installed backup light increased in popularity, a special switch was attached to the base of the floor shift lever. This was the only location possible as there is...

  During the late-1950's GM car and truck manufacturers begin to install optional V-8 engines in their vehicles. To set the vehicles apart from their six cylinders, V-8 emblems were designed to attract outsiders. This GMC front fender V-8 emblem above was used during 1955 through 1957. The GMC letters were on both six and V-8 trucks. The pictured Hydramatic...

  During the mid 1960's, most still considered pickups work vehicles. The manufacturer designed them as haulers and few people owned them as their only family vehicle. However, a slight change was beginning with truck buyers as Americans began to have more disposable income. GM and other truck producers were aware that extras on work vehicles were finding more buyers...

The 1967 Chevrolet and GMC trucks are noted for numerous one year only features. As the year progressed, engineers made several changes they felt were an improvement over this first year design. For reasons unknown, dash knobs were redesigned. The following pictures show the correct 1967standard knobs with 1.23 inch diameter serrated edges. Compare these with the 1968-72 knobs having...

  With increased prosperity in the USA during the 1960's the demand for more extras on cars and trucks was high. Manufacturers followed this trend with additional features, at least on their top of the line models. GMC followed this movement even though their product was mostly for work related duties. While sharing much sheet metal with Chevrolet, they certainly...

  To keep production costs down during the 1960-66 Chevrolet truck series, GM made very few changes on their ½, ¾, and 1 ton. Only the more skilled truck enthusiast can correctly identify each year in this series. Keep this following data close at hand when you evaluate these years. 1960 Dual headlights. The sheet metal part of this hood...

  When observing restored 1947-1953 Advanced Design trucks, we rarely see the removable dash parts painted correctly. Though at least half the owners paint these parts to their personal taste, many truck restorers want the dash appearance as original. Surprisingly, we rarely see two alike even on trucks that are said to be restored just like they left the factory...

  Though at first, a new person in the GM truck hobby might think all 1960-66 Chevrolet cab trim (only on the deluxe models) is the same. In reality no less than three changes occurred during this seven year body style. During 1960 (maybe into early 1961) the optional stainless cab side trim on the Chevrolet truck was designed to...

  During the early 1960's GM's majority of truck buyers chose the base truck with few dealer installed options. It was ending an era of very limited disposable income among the average US citizen. General Motors saw the trend toward more extras on trucks and began to offer visual extras such as two tone paint, side trim, and upgraded interiors...

Between 1954 and 1959 the dash cluster of GMC trucks were given a circular opening for a dealer installed clock or tachometer. These trucks left the factory with a blank-out plate to fill this opening. With most GMC's this plate always remained in place as an option was rarely added. The enclosed photo shows both plates used during the period...

By the 1960-61 years, the V-8 emblems on Chevrolet were not placed on the truck's doors or fender but were only on the nose of the hood. They were shaped different when the truck came with a 283 V-8 instead of the standard 235 six cylinder. The V-8 front emblems have become very difficult to locate. Most remaining trucks show...

On most all early GM trucks their fuel line exited on the bottom of the tank. It was usually attached to a brass shut-off valve which threaded into the tank. In case of fuel pump or line repair, a person had to lay under the truck to turn the tank valve and stop fuel flow. No doubt, this design resulted...

  The bed side trim moldings were used on the second year Fleetside Chevrolet deluxe pickups for just one year, 1959. General Motors waited one year after the Fleetside introduction to give their dealers time to sell all their 1958 Cameos (The end of this model) so there was not two deluxe designs available at one time. The bed moldings...

With the new Fleetside bed design in 1958 the Chevrolets placed a chrome emblem on the bed side with the word "Fleetside". However, GMC referred to this new bed as a "Wideside" to not copy Chevrolet. A Wideside emblem was never created, thus the GMC bedsides are without letters. NOTE: The horizontal long bedside trim is a 1959 option only...

  Among the many updates in the new Advance Design body style in 1947, one that certainly stands out, is the change in gas tank positioning. For the first time since 1936 it was placed outside the cab and under the bed. The dimensions of this 16 gallon tank were based on the limited space between the right frame-rail and...

  One of the rarest emblems of the mid-1950's is the 1956 Chevrolet Hydramatic front fender trim. A small percentage of '56 Chevrolet pickups were equipped with the Hydramatic, so many enthusiasts have never seen this item. At a glance it looks like the one used with the non-automatic and thus it is often over-looked. This is a very in...

What's this bad rap some people give the GM pickups with in-cab gas tanks? For 35 years GM protected these tanks from collisions by double wall reinforced cab metal, doors, and seat riser frames. The 1937-46 pickups even secured the tank under the seat and surrounded it on three sides by the welded to floor heavy gauge metal seat riser...

During the mid 1950's, V-8 engines began to gain popularity. Many became an option in full size cars and trucks that normally were provided with a six cylinder. When this occurred, most vehicles were given a body emblem advertising that the larger power plant was under the hood. GMC trucks were no exception. During the 1955-59 body style, two different...

  To help prevent metal to metal contact when 1/2 and 3/4 tons are overloaded or have weak shock absorbers, truck manufacturers used a rubber devise. This cushion prevents the axle from making direct contact with the frame rails. On the rear of the 1947-1953 GM pickups, it attaches directly to the underside of the hump in the frame. It...

  These are some very rare photos. It is quite unusual to find 1947-1953 Chevrolet and GMC 1/2 ton bare frames together. Here, you can compare the differences in the front cross members. As the GMC six cylinder is a few inches longer than the Chevrolet, engineers designed two different front engine cross members. In building the truck frame for...

  GMC bumper guards during these years were standard equipment and stamped from the same heavy gauge metal as the bumper (a different style and lighter gauge metal were dealer accessories on Chevrolet light trucks). A slight change in design was made at the end of the 1956 year. A more decorative pointed dimple was given the guards during 1957...

During 1941-46 a unique device was used in the front of both frame rails of Chevrolet/GMC trucks. It was designed to serve two purposes. This forged steel 'horn' was a spring hanger as well as a connection for front bumper braces. These horns are securely riveted into the end of the frame and were designed to last for the life...

  During the Advance Design years no less than four different Chevrolet hood side emblems were used on 1/2 tons. Each of their two mounting pins are in the same place so the punched hood holes were unchanged during these years. All were chromed die cast even during the 1952-1953 Korean war chrome shortage.
