5.0 Canvas top & seats

5.0.1 Ford GPW type seat cushions and back pads.

All canvas work was done at the Highland Park plant. Canvas items were made from heavy, water and mildue repellent, fireproof duck cloth.

The seat cushions and back pads were made at the Highland Park plant. Those of the GP were built of 2" sponge rubber covered by heavy-weight, water repellent and fire resistant cotton duck (canvas) The thickness of the 2in. cushions gave the driver ample room to handle the steeering wheel.

When the GPW model was under production, a zipper was incorporated into the cushions facings to permit the stowage of a blanket. This was necessary since shortly after Pearl Harbor, Dec. 7th 1941, the Government reduced the amount of rubber that could be used in the cushions, because the jeep was classed as transport, not a combat vehicle.

After December 7th, 1941, the sponge rubber was removed altogether and rubber coated curled cattle hair, 2in. thick pads were used instead. However,the rubber for coating the cattle hair was finally declared "out" by the Government and a spring type pad was substituted using tufted hair padding on top of the springs.
