A couple of things to think about. The truck has a lot of value if restored to stock specs. Avoid hacking up the dash, fenders, interior and other areas. Finding a factory front bumper and repairing a that rust should be major priorities. I doubt you will find an original rear bumper but a Fey Sure Step rear bumper will fit nicely. As for the engine, if it is in need of a rebuild then I would recommend getting a new crate motor. I know it is pricey but it will be cheaper in the long run. To get the truck back to where it needs to be will probably cost $10K but it will be well worth it.
