Crew cab on regular frame

[Lone Ranger]

I don't know much about bump crews but I know enough that I want one. I have never seen a bump crew but I know where a dent crew is. This particular crew is on a two wheel drive chassis and if I was to own it I would want it on a four wheel chassis. Is it possible to pull the crew cab off and put it on a regular (73-77.5)highboy chassis? Would it bolt right on? Or are there more cab mounts on a crew? I'd probably leave it a flat bed cause I know the wheel wells wouldn't line up. Thanks in advance
