if ur ball joints are in a bind its most likely the uppers. i had this problem when i did my setup for 20s. if thats the prob theres a 2 way fix. 1. u can pie cut the uppers and pull the ball joint down 1/4 inch. to do this, take the ball joint out and right behind it u will see were it starts curvin up. take a torch and cut around this flat spot. it should look like the top of an octagon when done. then right below were the back of the ball joint stops, take a zawzaw on the side and cut it square about 3/8 up the side, then measure 1/4 in over toward the front and cut back to the first cut line. then take a torch and heat right above the cuts and bend them down with a hammer then weld back shut(both sides). or 2. u can make a 1/4 inch shim plate that bolts in front of the control arm on the frame. both work well on this. i had to do both, but hope this might help.
