Pretty sure that '41 was the last model year trucks shared frame/suspension components with p***enger cars. Bob
Nohow. After '41, pickups were just trucks, simple ladder frame, suspension design adapted from early Mesopotamian oxcart. Many mechanical parts interchange, but nothing in frame or body.
Also, the '41 pickup frame was based on 1940 p***enger, and not interchangeable with '41 p***enger...WTH??
Ford Pickup frames were the same as P***enger Cars from 1928-39 and in 40-41 the Pickups shared frames with the 40 P***enger cars.
