When my car was totaled I had to buy a new hood. When I brought the car to the state salvage inspection station they checked the VIN #s of the car (front and back). The work was done in New York and it was a new after market hood and there was paperwork attesting to that. There was a pile of a couple doors and some wheels that had been confiscated because they were from stolen vehicles. So in MA there must already some sort of process for tracking this stuff. Won’t help for raw material and it’s probably not fool proof but it seemed to be something.
‘Bills of sale evidencing acquisition of all major component parts used to restore the vehicle. If the vehicle was wholly or partially restored with “used” parts, the receipts must contain the Vehicle Identification Number (VIN) of the vehicle(s) from which the part(s) were taken.’

The assumptions baked into your comment are probably the most Massachusetts thing I've heard all week.
The yard just has to check that the vins match the paperwork and that you match the name on the title.
Doors aren't serialized (models that put vehicle info on the driver's door not withstanding). Wheels aren't serialized. Those were sitting there because some employee wanted them, either for personal use or to sell.
