Why?
Would a 67-72 frame be a first choice if you had one @ your disposal & not being used vs. buying something different?
Because I have a 65 frame that's still .500" off from being square after coming home from the frame/alignment shop (I was going to use it for the start of a rolling chassis). I also have a 68 frame that isn't being used, is square, & already has the same mods I intended to do to the 65 frame done (It was free so I used it for practice
).
I'm going to measure differences today. My hunch is they're definitely close enough. I know from the bed back they are except for holes in the frame for incidentals (bumper brackets). I was curious if anyone here had actually done the swap & could detail their experience.
If they're close enough, I'll take measurements on the cab mounts to transfer them over @ the correct height/position. Then I'll cut the frame horns off the 65 frame & transplant.
