All good info.. As far as my bird goes I havent even considered rolling the fenders ... When I got my first bird 20 years ago the rear fenders were eaten up with rust so I cut them out and flared them so I could fit the old school n50-15 protracs under it. Too bad I backed into a buddy's car less than a week after and snapped one off.(lol) With this car it has the centerlines on it already and the back spacing is maxed I will probably just switch rear wheels to maybe an 8" dish and 255's .
