On the "Ship Of Theseus" theory: if I were to swap my rusty frame on my NAS 1990 Range Rover with a new frame from England, who would it have to be checked with since it no longer has a VIN number on it? If I had to replace the block with one from Chad or bought a new one from BP, it wouldn't have a matching vin, if any at all.
Now that I'm down two of the OEM VIN plates, would my truck pass a level 3 inspection at the DMV if there were questions about it's heritage?
As it turns out, the last Pennsylvania title had a typo in the VIN. It came to Az with me and the VIN on the PA title was entered into the AZ system (which didn't throw a checksum error, btw). It wasn't until two years later at an emissions check that someone caught it. Went down to DMV, I think they only did a Level 2 inspection, corrected the title and issued a new registration card and I was on my way. I think he only looked at the door plate and the dash plate. I don't remember him crawling all through the truck for info.
Since my truck was imported by LRNA through Houston, I'd feel more confident on having proper background records to verify the truck. But since Frank imported his own truck, how many parts could he swap with newer model or new parts before his truck is in the gray area?
