How DeLoreans Were Originally Built, Stainless Panel Discussion

[Pags44]

I would like to open a discussion regarding how the cars were generally put together.
*
When the cars were originally built, were the door panels (and other stainless panels) packaged together for a specific car so all the stainless grooves match throughout the car?* Or were any available stainless panels taken and put onto the car?* Were there certain production runs of stainless panels made for certain cars or groups of cars?
*
My car’s driver’s side door has my VIN # written on the inside of the door in what seems to be black marker.* I understand “cave drawings” and builders’ signatures were sometimes written on the car parts by the workers as they were putting the cars together.* Is my VIN # being written on the inside of the door a common practice to identify the door to the car with that specific VIN #...or something a worker randomly wrote on the underside/inside of it (on the stainless behind the vinyl interior panels)?* The inside of my passenger side front fender also has a signature.
*
What happened if panels were damaged on the carrier before the cars were delivered to the dealerships or customers?* What replacements were used?* What is the process if any stainless panels ever get damaged and need to be replaced…can the panels (and their grooves in the stainless) be matched to the rest of the car…either by matching replacement panels, doors, or regraining the entire stainless on the car?
*
Thought this would be a good discussion...
