I have a quick performance ford 9" in my car and didn't have any of these problems your saying? The only issues I had was the lower shock mounts. A quick "tweak" and they are fine.malicad said:Didn't anybody read all the problems everybody is having with the brackets and the upper control arm mounts not lining up with QP rear ends? It's cheap crap. You get what you pay for. Buy from Currie or Moser and rest assured you have something nice.
