Steve89, do you think that those fenders are 100% fiberglass, I wonder if someone "glassed" the inside of the steel fenders to cover Swiss cheese or for preventative measures? Those style fenders were a three year run, I have doubts that an aftermarket item was available, would be no profit in them.
