I'm going to be redoing the rear housing on a buddies Gbody 9", and adding adjustable control arm mounts for the upper and lowers. We're also going to build some rod end style lower control arms. I notice on his aftermarket upper arms, the U shape connection point hits the housing when he tries to run lower ride heights. What uppers do you G body guys run, or how do you eliminate this on your lowered G bodies? As well, I'm looking to see if anyone has the math data for the mounting points on the chassis side, so I can plot this rear suspension out and calculate the antisquat values. Thanks for any help you guys can give.
