alignment woes ..offset bushings

You don't need to unload the T-bars. You could jack underneath the outer LCA to hold it at the neutral position where it would normally be with weight on the wheel, and to keep the UCA off its bumpers. After replacing bushings, don't tighten the cam bolts until the UCA is at its neutral position, otherwise it could shear the rubber if tightened when hanging down. Since in CA, you won't have all the rust problems others fight with. I coated my cam bolt shafts w/ grease so they can't rust-lock to the bushings.
