I have did the final fitting on the challenger fenders yet, but the quarters do need work to fit up right. Can't expect it to fit perfect, but theres alot of room for improvement. The parts are pretty straight and not too thin, which is a big plus. I have two ways to look at parts, on one end for my own cars, I'll fix rough original parts, my time cost me nothing. For customer cars, I prefer new stuff that wont take as long, well up to them, but helps keep the cost down, since my time is money to them.
