Torsion Bar Not Seating

I replaced bushings on my front end some months ago and hard a hard time getting the drivers side TB to seat. The LCA looks like it was replaced at one time (painted black where the passenger side looks stock). Passenger side bar went in just fine. I knew I was going to replace the OE bars with PST bars, which I did recently. After replacing the bushings, I had the car aligned. The shop said the driver side was tweaked a little and the car was not square. He aligned it so it drove straight. When I recently replaced the OE bars with PST, the driver bar also would not fully seat (about 1/2" sticking out of the LCA socket). I did not want to pound on it too much either, so took the car to a frame shop to have them check for the car being straight. They said the measurements were fine, but could not find a reason why the driver side bar would not fully seat.
Any ideas?
