The only # used in 1946 for ID was the motor # located next to the distributor. Two small hexagon clutch head (8-32 X 1/2") threaded screws were used to mount the ID plate on a tag on the passenger side firewall under the hood. See photo for location. The I.D. plate — every GM truck had one attached at the factory. Basically, it states the vehicle’s gross weight limit (weight of truck plus its maximum allowed load) plus stamped digits that give the assembly plant year, size of the truck, month built, and sequential numbers as it came off the production line. These plates are necessary for positive vehicle identification.
