disc conversion then alignment no good

Take it somewhere else. Someone who knows how to do a performance alignment. Those numbers may work for Grandma's Dart. Camber should be -1.5, Caster should be +2.5-3.5, Toe in should be .06 to .12 for a High Performance street car. I've done this many times without offset bushings. Get a good, if not the best, MOPAR alignment guy in your area. What kind of tires are you running?
