Ford used the term Commercial for the 1/2 ton which was built on the passenger car type frame. "Pickup" was an owner added reference. The larger trucks were all identified by wheelbase length, type of bed, and cab placement. There were different model numbers to ID how they came from the factory. Variations in wheels and tires plus use of helper springs gave them more or less gross weight capability. Most trucks used the same transmission, clutch, and the old Timken rear axle in that time frame. They may or may not have dual rear wheels.
