Default Understeer only to the Left

I have a 71 Lemans that has a 70 front clip (big chrome bumper) that may have
been wrecked - don't know the history, but no evident frame/body damage. I had an alignment and the guy said he couldn't do the driver side right because there was not enough adjustment. At the time, I didn't know enough to ask many questions but now I know a lot more.

Right side is +2.0 caster / -0.5 camber and handles properly. Alignment guy left the alignment screwed on the left side +3.25 caster / -1.75 camber so I figured that was the under steer problem. Using a Bubble Alignment tool ($20), a lot of adjustments/drives, I now have +2.0 caster / -0.5 camber on both sides. Don't know about toe in but the alignment sheet was in specs to start with.

Still have under steer - tun left and it won't straighten up on its own. Only other things I noticed were :
1. when jacking front end dead center, the driver side hangs about an inch
plus lower because when I just get the R side jack in the L side requires more
pumps to clear the stand.
2. When in park, the steering wheel rotating to left is really easy but to the
right requires noticeable more effort.

Just been living wih it. Any ideas ? PS pump cause this ?

Thanks
