I would *guess* that would be for the early frame, 1960-1962 with the coil spring rear and trailing arms. Most likely due to where the trailing arms pivot from on the frame.

You can see that the pivot point on the early frames is just forward of the rear of the cab, (forward of the rear cab mounts) so you would have to cut the frame under the cab to shorten it, unless you wanted to get into cutting and re-engineering the trailing arms **if you had a 1960-1962 frame**

Also, the '60-'62 trucks could be ordered with leaf springs under a rpo (regular production option). My grandfather ordered all of his 60-62 1000-1500 series trucks with them, only after receiving the first few 1960 mdls with the coil spr rears.
