If you have time, I used to sit in my car while the alignment guy adjusted the height and alignment.

That was along time ago and people didn't sue shops for breathing on there cars so it may not be an option now.

If he isn't used to old school T-Bars, make sure he knows to loosen the LCA pivot Stud before he adjusts the height and tightens it afterwards. You don't want to leave the bushing in a bind at ride height.
