Good question, I have a set of both and there are only small differences between them. On the front fender, there is a raised lip around the well for the fender light. On the repop, the lip is smaller and does does not run the fulllength of the light...kind of tapers toward the back. But that could be a matter of the person finishing the fender and others may be closer to the original. The ducktail on the repop front is just a little shorter than the original. The originals feel slightly heavier and the overall QC and attention to detail is a little better.
