I want to drop the front end about 1/2". I adjusted the torsion bar bolt. Now the bolt is about 1" completely away fron the torsion bar arm. If I bounce the car up and down it dropped the 1/2" but not all the way back down to the set bolt. What would be preventing it from dropping. On a side note this is a 74 Barracuda with a 340 and I have replaced the shocks, bushings and ball joints. The car was undercoated back in the day. So I'm not sure if it's rust, bushings or the undercoating. Or a combination. Should I be using liquid wrench to loose anything? Thanks!
