what do you have? 1/2 ton, 3/4 ton 1 ton? what are you going to do to the truck?? need more info.
the axles between trucks are pretty much a bolt swap job. not sure about the drive shafts, never seen if they fit or not. but the suspension is the same. I know on a 94 there was 2 different widths of leaf springs. so might watch out for that. Not sure if the 97's had that set up also.
