1966 cab features

Curved Windshield

The large one-piece laminated safety plate glass windshield has an area of approximately 1116 square inches.

Electric Windshield Wipers

Provide constant wiping action regardless of engine load or accelerator position. Wipers have 13-inch blades and a wiping speed of 110 strokes per minute. Two-speed wipers, including a push-button-operated windshield washer, are standard. Wiper arms and the metal portions of the blades have a matte finish.

High-Level Ventilation

Outside air enters through louvers at the top of the cowl – away from road dust, heat and fumes. The air passes into a plenum built into the the cowl, where water is separated from the air and drained out. Air enters the driver compartment through two inlets-one on the right side and one on the left.


Partial opening of ventipanes permits stale air to be drawn out of driver compartment. Ventipanes can also be swung wide open to force outside air into the compartment. Made of solid safety-sheet glass.

Rearview Mirrors

Standard mirrors on Pickup models are a left-side fixed arm and an inside shatterproof. Series 10-30 Chassis Cabs utilize left- and right-hand 6-1/4 inches fixed arm standard mirrors. Series 50-80 models have a left-side 17-1/4 inches swing arm mirror as standard. A wide assortment of optional mirrors is available on most seines. See the Optional Equipment listing in the Model Specifications sections for exact availability.

Full-View Rear Window

Available as an option at extra cost. Large solid safety-sheet glass area of 762 square inches (331 square inches for standard solid safety-sheet rear window) improves rearward visibility to make driving easier and safer.

Safety Glass

Series 10-50 models have door windows of solid safety-sheet glass. Laminated safety sheet glass with metal window frames is optionally available. Series 60-80 models have laminated safety sheet glass with metal window frames as standard equipment.

Soft Ray Glass

Tinted glass is available as an option at extra cost. It may be ordered for the windshield only or for all windows. Consult the model specifications pages for availability as it varies with the series. The light and heat absorption of this glass reduces eye-strain and helps keep cab temperature more comfortable.

Window Frames

Painted metal frames on series 60-80 give extra rigidity to windows and reduce likelihood of broken or cracked glass. Metal frames are also included with the laminated glass option on Series 10-50.

Door Locks

All cab models include a key-operated left door lock as standard equipment. A right door lock is available as an option at extra cost.

Running Boards

Cabs in Series 50 through 80 are fitted with a running board on each side for ease in entering and leaving the cab. LCF cabs also have two convenient steps on each fender.

1960-1966 Chevrolet Hood Changes

Thursday, February 11th, 2010

1960 1966 hood changes 1

The two distinct styles of hoods during this seven year series (1960-1961 and 1962-1966) were each the same for Chevrolet and GMC except for one slight difference. The spot welded insert across the front (5″ x 82″) is a different stamping for Chevrolet than for GMC. This created a changed appearance with less expense!

Because of this different insert the two trucks have park light lenses that will not interchange. For economic reasons the 1960-1961 style hood was soon discontinued by GM. After the mid 1970’s, if the dealer ordered a 1960-1961 hood, he was sent the 1962-1966 style. It fit the older design truck perfectly.

For the non-perfectionist, all 1960-1966 GMC and Chevrolet hoods will interchange.

Rocker Panel Moulding Instruction

Thursday, February 11th, 2010

Yes the cabs are the same between 1/2 ton and 2 ton on the 1955-1959, however one extra does exist on the 1 1/2 and 2 tons. These larger trucks have an additional rocker panel! Their panels are held to and cover the regular rocker under each door with nine sheet metal screws. They even extend from the under door area to along the edge of the cab corner.

Check this page from the 1955-1959 Chevrolet Factory Assembly Manual printed in those years.

Their 1956 Chevrolet 2 ton had them missing and the truck was obviously lacking something. They discovered the problem when they found this page during their research.

Fleet Side Steps

fleet side steps 1

The convenience of reaching cargo is ideal in a step bed pickup. The step between the cab and rear fender provides a place for the loader’s feet while reaching into the bed. Thus, this pickup is referred to as a ‘step bed.’

With the introduction of the fleetside box in the late 1950’s, there was no step. Placing cargo in the bed became much more difficult if added from the side of the bed. With some complaints, GM realized there was an opportunity to market a unique dealer installed accessory for this newer truck. A cast aluminum step was designed to actually fit into the fleetside sheet metal. Once the correct hole was cut in the bedside, the new step made access to cargo almost as easy as with the stepside. These were introduced in the mid or late 1960’s. They are a very rare item!
