I am now thinking that the HDs are non-adjustable. I just went out this morning to check the height; both sides are now identical. Settling of the springs/shocks?

By the way, Bilstein HDs are profound improvement in handling. Ride quality is much more firm but far more composed. No more massive bobbles on railroad tracks or bridge approaches.
