'66 Barraduda front suspension won't adjust down one on side

Hi, I noticed my '66 is sitting higher on the left than the right side.
I backed off the adjusting screw on the lower control arm to the point where it and the little crossbar it screws into are actually loose in the arm, meaning the adjusting screw is no longer contacting the torsion bar arm. The ride height didn't move down. Turning the right side screw adjusts the suspension up and down just fine. Bouncing the suspension shows that the torsion bar is turning. Might it have been clocked too tight during assembly at the factory? I'm sure everything is original, so removing the torsion bar would likely be a challenge.

Any ideas would be appreciated!

All I can think of is to replace both torsion bars . It sounds like the left side twisted for some unknown reason. I say change them both so you don't have the same problem but opposite . the new one would be stronger than the old one. Do it right the first time so you don't do it twice. My grandfather always said it takes a lazy man to do it right the first time and an ambitioned man to do it over and over again. LOL
