mnrookie Posted March 18, 2013 Report Share Posted March 18, 2013 However the 8.5" posi is hard to come by and gets expensive. If I remember right they only came in the buick regal t-type, grand national, gnx and some 442. The 7.5 is weak for the track and street with sticky tires if putting decent power to them.
