[71blksuper4x4]

For a purist, the 71 cab has subtle details different than that of a 69'. It depends what you want to do for a restoration. The 71' rear view mirror mounts on a raised pad, and to my knowledge is the only year that this raised area on the cab exists. The 71' will also have a vent by the vin plate in the door jam and not on the 69'. The 71' being a Cheyenne means it has the headliner holes punched in the roof, and the 69' (unless a CST) will not. Like I said, if you don't plan to still make it a 71' Cheyenne, I wouldn't worry about it and use the 69' cab. With using the 69' frame, it wouldn't matter anyways for a stock restoration under the 71'. Good luck with what you decide, sounds like a fun project. Trevor
