I removed the bolts completely, put a nice coating of white lithium grease on them, then started from scratch and counted full revolutions to match them up. However, this still resulted in my driver's side sitting a full inch lower than passenger side. I had to get about 6 full revolutions difference to get it to sit at an even height.
I'm assuming this is from battery and driver being on the same side and the torsion bar has yielded perhaps due to the increased load vs passenger side. I reached this conclusion also in part because this was at the end of my project to replace control arms, shocks, bushings, etc on both sides, so it wasn't wear anywhere else in the suspension system.
