80' C30 chassis and drivetrain swap

[OldGMJon]

I want to swap a 64' C30 cab I have onto my 80' C30 chassis. The 80' cab is toast but as you can see I have a very nice 64' cab that is a good candidate for the upgrade. I will be utilizing the chassis and complete engine, drivetrain, and suspensions from the 80' and the diamond plate bed will be a good match too...just mounting the 64' cab onto the 80' chassis. The difference in the steering boxes makes me think I should use the 80' steering column as well. Is this a bolt-on possibility or will there be some modifications involved? I will be swapping the front chassis tips so I can retain the 64' bumper but wonder what other modifications will I be experiencing by using everything 80' underneath? Thanks for any help you can give me on this build.
