The 67 and possibly 68 (not sure) used a ram assist. In 69 (?) GM went to the "normal" PS set up with a ps box onstead of a ram assist. I dont think PS became standard til 1988 (?) I have never seen a post 1988 truck without PS. 1973-1987 truck boxes will mount to the 69-72 frames, but GM changed to metric lines around 80-82 (?). 67, possibly 68 frame is different.
