Mine rides and drives just fine. I didn't have the front end aligned ust put 15's on the back and kept 14's on the front. To properly align mine I would need more positive caster. something Mopars are short on. As long as it drives straight and I can let go of the wheel and it doesn't pull I'm ok. I was going for the look.
I like that rack look, but to a limit! I am considering a side exh like the aar-t cars. These f bodies have a problem in 76 with dual exh and the tank of that yr., so some rake helps that.
