Recently purchased a 1968 short box 4x4. Previously owned several 73-91 and always loved the 67-72 style. I know the truck is not original, but trying to find out some of the history. The previous owner had not done the swap and told me what little he knew. It was a 2wd 68 body place on a 4x4 frame and titled as a 68 4x4. Anyone know how to tell the differences in frames between 67-68 and 69-72? I've noticed they make lift kits for 69-72 but not 67-68? Thanks!!!!!
