im not completely sure but i think the 68 has narrower springs. any particular reason you are swapping to the older frame?

68 frame has longer rear springs, your better off with a shackle flip. Also the front axle is drum, closed knuckle so finding parts is near impossible. Other than that there are small differences but you shouldn't have much issue.

well im throwing a 14bolt and a 60 under it, and the frame on the 71 is in rough shape

Just the set up I have. 71 cab on a 68 frame with D60 and 14 bolt.

Not really a big deal if the lift uses rear blocks. I assume you will be running traction bars so axle wrap due to the blocks will not be an issue. I run a 68 k-20 frame with the 69-72 4 inch lift (front springs and rear blocks) and it works fine. The 68 rear springs are 56" long and are wider at the eyes than the 69-72 versions.
