if you are not useing the bed you would not need to shorten the frame just build your bed to fit but if you can get a 67 to 72 it would be alot easier

its just the mount for the bumper that is different on the front of the frame you could find a junk 63 to 66 and cut the front frame horns off and weld them to the 67 to 72 frame pretty easy you only need about 3 to 4 inches of a 63 to 66 frame don't use a 60 to 62 cause they are different

change the rear cab mounts on the frame and the body will bolt right on the 67 to 72 frame

and the radiator for the 63 mounts to the cross member and in 67 to 72 trucks it mounts in the core suport you can swap the crossmember if you want to run the 63 radiator but it probably wont cool a cummins or a big block anyway

the bed will bolt right on as well as long as its the same bed length

i have a 63 on a 70 4x4 frame and i am putting another 63 on a 2x4 68 frame now

in 67 the frame was made for power steering so a power steering box from a 71 to 87 will bolt on (i was told that 67 and 68 trucks need a .025 shim between the frame and box but i can't say for sure on that yet)

the frames are pretty much the same from 63 to 72 just the above differences but it is real easy to swap bodies between 63 to 72 trucks

and 62 was the last year for the apache
