Only issues I had were with lower ball joints....didn't fit due to too much 'meat', had to grind them down a bit b/c they hit the backing plate. May have not been an issue if I had disc brakes in the front tho.
Also, unless they changed something, their 1.03" torsion bars are not clocked or indexed properly. So the front end is lowered quite a significant amount. About 3-3.5" of suspension travel from bump stop to frame.
Otherwise, everything else was great!! Especially with the Firm Feel rebuilt power steering chuck!
69 Coronet, front drums, PST poly front end rebuild kit and 1.03" dia torsion bars
