I would hire one of the top Shelby judges in the country to go over the car in my presence if I was ever to buy it.
Photograph and document everything. Just my opinion.

This is probably a good discussion for all collector cars in general, because the NOS parts are so valueable for all cars that harvesting them off the car and Repop replacements is big $. The average consumer would have no idea.
The people hunting down and paying for these NOS parts are passionate about NOS vs. Repop - that is what seperates or gives distance from one cars quality vs. another.

I could easily see a person looking at a car for sale on Friday, buying the car on Friday, having the car delivered the next Friday with different Repop parts that the average consumer would not know.

Like Les said, get a judge to check the parts, then it would be settled. He was in no way degrading the car, just stating written Registry facts.
