Using a panhard bar is a good way to bind the suspention up on an A/G body. I have had a few A bodys over the years....still have 4 currently and all I have done is trim the inside quarter panel the small amount that the rear is shifted over and done. If they still rub or touch get a hammer and beat some clearance into it....or come to the conclusion that the tire is too big and get some smaller ones. 10 pounds doesnt always fit in a 5 pound bag. My 79 wagon has had 295 50 15's slammed with moroso coils in the rear and 28x12.50 MT ET Streets with no issues at all....no extra bars no nothing. If you push on the quarter panel of the car and the rim/rear end doesnt move with the body or "floats" side to side the control arms are garbage. With solid bushings or good urethane bushings there should be absolutely no rear end movement...peried. And using a radial street tire or radial slick will cut down on tire movement and growth.
