Yes, I agree that's the most likely the issue with them hitting the frame.
Also, has the frame been repaired above that adjuster arm.???
A month ago I saw a high dollar 70 hemi cuda vert clone that had that same T-bar adjuster to frame hitting. The T-bars were installed on the wrong index and the frame had a bunch of horrible rust repair plates added. Also there is supposed to be a reinforcement for the lower control arm bumper on the frame that was missing in this totally miserable repair job.
