That is an exceptional help actually. He desires a completely modern running gear and my frame has a nova subframe spliced to the factory frame and he will be using a V8 and auto transmission, so as long as the wheel base is correct and the bed and cab fit it should be good!...

Do your books go off serial numbers like the tags on the cowl or the numbers off the engine block?

His is a GMC so unfortunately I do not know if his is the equivalent of a 40 chev or if GMC was completely different though I doubt it, or was a year behind like it is currently in the sheet metal department.
