1972

GM’s first year for optional “rear” air conditioning! Thus, on the 1967-72 Suburban series, this is a one year only design. Prior to 1972, the Suburban’s from GM and some aftermarket companies sold a long unit “down the center” of the interior above the two rear row of seats. (The original in dash unit also operated.) No doubt tall people...

Our Featured Truck of the Month (a 1972 Chevrolet Cheyenne Super) is the final year of this classic body design. It has never lost its popularity! The 1967-72 GM pickups are the ultimate result. GM began the transition of a farm truck to some luxury trucks in 1955 with the introduction of the Chevrolet Cameo. This was GM’s test to...

The 1967-1972 - What's That Noise? Gaining speed after you turn onto the highway, your GM truck (1967-1972), moves toward a cruising speed equal to the surrounding traffic. As your engine reaches about 2,000 rpm you suddenly hear a low hum up front. It does not stop as the truck speed increases. If you lower the windows, play the radio...

During 1972, a unique Chevrolet promotional pickup was introduced for a limited time in 1/2, 3/4, and 1 ton models. This truck was designated the 'Highlander'. Unfortunately, it did not have side emblems or related name plates that would cause people to remember this special model. On the actual truck the word Highlander was only listed on the glove box...

During the late 1970's, trucks accelerated their change from a more commercial work vehicle to one desired by the family as their everyday transportation. During 1967-1972, Chevrolet and GMC introduced names such as CST, Cheyenne and Sierra Grande to show buyers that their trucks were no longer just for work. Options that rivaled cars could now be ordered for their...

Are you on a hunt for a new 1969-1972 Blazer tailgate? It may not be as difficult as you think. GM saved much money by using a 1967-1972 Chevrolet Fleetside tailgate! The one difference is a narrow strip of stamped sheet metal attached to the top edge. Most used Blazer tailgates, whatever their lower condition, still have this strip. This...

In recent years seeing the unusual Chevrolet Longhorn or similar GMC Custom Camper (1968-1972) has become a very rare occurrence. These oversize pickups, with 8 1/2 ft. bed floors, were built for work and thus there is a very limited survival rate. Most seen today started life as they were advertised carrying a vacation camper. They were usually more taken...

1967-72 Chevy Truck Model I.D. We hope the following information on Axle, Transmission and Model identification will help many of you with your questions. Accuracy was a concern as we compiled this information. Because GM made so many scheduled as well as unscheduled changes, there is much discussion about these changes. The following is used by permission from Pickups and...

These years are the 'last of the breed'! Due to the increasing popularity of the new G-series van, panel truck sales had continued to suffer since the mid 1960's. By 1970, General Motors panel truck production came to a halt. GM did not even wait until the end of the body series in 1972! This 'enclosed body on a pickup...

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...

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...

  The 1968-1972 hazard flasher unit is not self canceling as in 1967. The only way to cancel the later hazard flasher is to pull the knob out. This feature was incorporated into the 1968 truck so that the hazard flashers could be operated when the vehicle is being used for slow speed operations. It became a problem in 1967...

  One might assume that because the 1967-1972 cabs are the same, there is also no difference in the doors. Yes, they will interchange, however, there are several visible door differences for 1972. During this year only, a countersunk hole exists in the interior door panel several inches from the wing vent vertical post. A Phillips screw here helps prevent...

  This original, well worn, glove box decal was recently uncovered in a salvage yard. It relates front hubs on a four wheel drive and how to engage and disengage them. Our 67-72 experts have never seen this decal. Can anyone tell us if this was a factory decal or just added later when replacement hubs were installed? Please contact...

  It was during the 1967-72 years that General Motors began offering more style to their pickup truck line. Though most still considered a truck as a work vehicle, a growing segment of pickup buyers were being strongly influenced by trim and accessories that even rivaled many automobiles. For the first time on GM fleetside pickups, decorative trim became available...

  The main cross grill stamping making up the 1967-1972 GMC grilles may at first appear the same but they definitely are not. The more noticeable difference is the large GMC letters stamped in the center of the 1967 grille (one year only). Therefore, these three letters are not placed on the hood front as during 1968-1972. Between 1967-1970, the...

To make the base fleetside tailgate just a little different from Chevrolet, GMC kept their letters body color and surrounded them in a contrasting color. On Chevrolet just the letters have the different color. 1967-1972 GMC (above) 1967-1972 Chevrolet (above)

  How did this happen? Strange but true. The 1971-1972 right front Chevrolet pickup fender has one of its two 350 emblem holes punched incorrectly. This causes the horizontal emblem to slope down at the rear. The left fender is correct. The person that owns this all original 1972 truck states that all 1971-1972 Chevrolet trucks have this unusual feature...

One of the most unusual features of the 1967-1972 series of trucks is the unique placement of the 1969-1972 Chevrolet Blazer and GMC Jimmy radio speaker. Unlike the pickup, Suburban, and large trucks; the radio speaker is not under the top of the dash. In fact, the dash does not even have grille slots to allow sound to come from...

My truck began life as a 1972 3/4 ton Custom chassis cab with a 350, heavy-duty camper suspension and four on the floor. I purchased it new in November 1971, and by February 1972, I installed a camper body on it. It remained this way until 1995 when the camper body was no longer reliable, having developed some fatal leaks causing some structural weaknesses. It was no longer practical or economical to keep it as a camper. I was faced with the dilemma of what to do with it.

First I would like to thank all of you for great service and quality parts.

Maych is a 1972 GMC Sierra Grande 1/2 ton pickup. He is named for my father, Martin Hamilton Patterson. I was 2 years old when my father died in an automobile accident, so I never really knew him. But for as long as I can remember, when friends or relatives spoke of my father they would always call him Maych.
