Does the later front crossmember bolt in? And what about the rear suspension? If I find a 1/2-ton truck, it's actually gonna be easier to swap the bodies out, to me. A 3/4-ton would still require the disc swapped out. I'd rather unbolt bodies, I think. If I have title to the earlier truck, it retains the title. If it doesn't, in OK, you can run the VIN stamped on the frame. You have to have proof of ownership of both vehicles. Plus, there is always going the route of an "assembled vehicle" and get a state-assigned VIN on it. I'm not worried about that aspect.
