I bought my 72 6 months ago and after swapping engines and getting it painted I finally brought it home. I bought 17 x 9 torque thrust 2's 5.5" bs for the rear and anticipated no rubbing issues. I drove the car home from the paintshop(only 4 blocks) and heard something rubbing. To my dismay it was the shock stud eating the inner wheel lip. The car had 2"lowering blocks on it. Not uncommon, but why the hell would there also be adjustable shackles in the back? Why try to drop and raise the car at the same time? I pulled the blocks and relocated the spring to the hole nearest the frame until I get stock replacement shackles in.
