Went and looked at a 56 GMC that has the NAPCO 4 wheel drive conversion, It is missing everything forward of the cab ie engine, sheet meta,l radiator, steering box, is a big window cab, decent doors and box, that needs new wood. He is asking $1800 and the NAPCO stuff appears to all be there including the transmission. I don't know if that is a good price or not.. Is all apart, and doors are just shells, but doesn't appear to be much rust anywhere. I have a 56 truck that the NAPCO will fit under
