69 Barracuda front RMS suspension issue

just bend it. or clearance the wheel with a hammer.

kidding, kidding. you probably, might, maybe get away with less backspace. try putting on a 1/4" spacer and see if that helps. a narrower rim may also be a solution.

a lot of 17" rims foul the outer tierod, and that's the reason most people step up to 18's when going for larger rubber up front.
