When a friend rebuilt a truck (quite a number of years ago now) he had to keep track of where he got his parts.... I think showing receipts was a big part of it. That was in Michigan.
I've done several in both N.C. and Md. In NC they send a Trooper to your house to inspect it and in Md you take it to Dmv where the Trooper VTU has a building. In both situations if you buy parts from a salvage yard you're good to go but if you buy from a private party they will send you walking if the bill of sales for used parts aren't notarized.
