1972 chevy

[junglejim]

ok guys I bought a 1972 chevy swb 4x4 that someone stuck a 1973 to 87 frame under it. I found a original 1972 swb 4x4 frame and powder coated it and the axles are done and is all setting on a 4 inch spring lift front and back. well my question is my cab I have is a low hump and it set on the other frame just fine because someone modified it. it has a 350 automatic with a np205. my first question is will this cab set on the new frame or do I need a high hump. and if I do need a high hump are all cabs 1967-72 the same and will bolt on to the frame. I guess what i'm trying to say is all the cabs the same other than low and high hump
