well, I'm starting to think I need to try to find someone with genuine RS front fenders and try to borrow them for molding purposes. This is turning into a clusterf*(%
Mounted the bumper......NEWS FLASH! The RS fender's nose is much more "flat" than the standard fender(which has a bit of a curve to it)
pic from below:
so I traced the line of the bumper, and went at the fender with the grinder to cut the curve out of it. Then I welded a flat patch behind it so I could smooth it all out with fiberglass and body filler.
definitely not excited about how it's coming out right now, and would MUCH MUCH rather re-mold an OEM genuine (not dented to piss) RS fender set. Fantastic, I'll have to do this all over again on the passenger side. :-/
