I would not call it a fake, it is obviously a fender.

It just does not appear to be a factory installed fender. Lack of sound deadener, the part number for the NOS system & the cars were painted with the valance on, then it was removed & re-installed after the bumpers were put on.

So, it looks like a used replacement fender to me. Rolling them with baseball bats was also a common owner trick back then for fat aftermarket tires.

I have still not seen any proof of rolled fenders from the factory.

If someone has some, I am sure that we would all love to see it?
