72 cab and door interchange questions????

[tll74]

Hey guy's I'm searchiing to find out the differnces in the 67-72 cabs and doors.
For the cab: I realize the differences such as high hump-low hump, cable throttle-mech. throttle, and ac-non ac. I'm redoing a 72 with a bad cab. I have a 70 cab and a 71 cab. The 70 cab is VERY nice and the 71 cab is rusty but repairable. What are the differences in these cabs compared the 72 cab?

For the doors: I have the same questions for the doors off the 70 cab and 71 cab. I realize the 72 only regulator, handle post to open, trim panel and recessed screw below vent glass. The 70 doors are mint in original paint. The 71 doors are rust free but dinged up. So.......are there any differences I'm not seeing?

I really want to keep this truck "correct". Thanks for looking.
