Frame swap between two chevys?

i have a 1990 chevy single cab long box i would like to put on aa 1970 era frame. it is also a single cab long box. they are both 4x4 frames. will the cab mounts of the 1990 fit onto the cab mounts of the 1970 era frame.Frame swap between two chevys?
Prolly not, that later era started in the 80's. But if you do, remember most states vin the frame, not the cab. So your truck may have to be a 1970's
