I will be doing the same thing 74-80 front on a 81-87 cab. As I was talking to someone you will need the hump from the 4x4 cab welded into the 2wd cab. Clearance for the transfer case. My 4x4 cab is also shot, but my daily driver right now has a good 85 2wd cab which will be going on my 74 4x4 build. I am doing a complete overhaul myself. I am working on boxing in my frame filling all unused holes, timely process. I hope it will be worth it and not to stiff. I am using 2 frames and making 1 that way all holes will line up.
