In my opinion, a "rebody" is the same as a "VIN swap" and should be handled the same.
I agreeBut lets play devil's advocate for a minute:
Lets say a car is a complete rust bucket or had/has been totaled or was a previous track car (drag or road race) and it requires all new floors, firewall, inner & outer quarters, windshield and back glass channels, dash, trunk floor, trunk lid, doors and fenders. Would that not be considered a "rebody" if all or most of those parts were replaced either with NOS sheetmetal or not? I guess ultimately my question is how far is too far..??..
