You need to measure and try to see finished photos of similar applications to determine the route you want to take. I mounted my 1951 on a 1978 1-ton frame though not four wheel drive. It would also be benificial to actually see a vehicle in person to determine what issues the other builders have encountered. You con look at the post below that was discussing a similar issue. Research is the best place to start and this site really helps.

other posts about frame swaps that might fit your application.
