So I've been looking at what I got, 1 crew cab is OK, new rockers and good to go. Its a 88 crew cab. Looking at the frames, theres some indents where the 2wd crossmember is that is different, 4wd is just straight. No 4wd rear spring perch hole or bracket obviously, front spring perch would need to be swapped out. Not sure what has to be done about main crossmember, its obvious ly different. Just a thought, Ive done front suspension swaps before on car frames, really no different. Cutting the frame scares some, but what do you think stretch vehicles have. Thinking of cutting the front 4wd frame behind the trans crossmember, adding a section from donor frame making it a crew cab and lining it up with the rear frame at a point to make it a shortbed at same time. That way, I can keep the Dana 60 i have, the T400 and NP205, and corp 14. Only need a driveshaft, not sure if shortbed conversions use a 2 piece. Any thoughts?
