I was reading in a catalog the other day, and about their repro fenders they said something like..
Since these are imported, they'll probably be scratched up, have dents, and won't fit right without jacking with them for an hour. Not our problem, it's yours.
I've talked to some guys who say they just slap right on, primer and paint.. i've talked to others who said the repro fenders were a nightmare.. dosen't seem to be any rhyme or reason to it.
