Check you toe settings through the full range of motion. When your accelerating the front rises depending on the loction of the rack ( up or down) compared to the rod ends will either move the steering arms in or out changing the toe. The other thing is when you lay of the throttle and or hit the brakes the nose dives so check it with the nose down slightly from normal ride height. If you have rod ends on the end of the rack with spacers you can adjust the toe at differant positions to get toe right. The other thing is 90/ 10 shocks will help with the nose dive dont run stock shocks especialy worn out ones. Next ? did you just turn the ball joints and steering arms around. That will put the spindal off center of the king pin angle. and will screw up your Ackerman angle also making the outside wheel turn at a sharper angle than the inside causing scuffing when turning. I hate to advertise here but I make tubular K frames and bolt on steering arms to correct these issues www.gofastmopars.net. Go look if I can help further please call or e mail me. Sorry if any of you are offended by me throughing in my web site. Just trying to help
