Your shop is retarded then, it is a bit of a process to set the caster/camber properly, but not impossible. There are a few different thicknesses of the shims, according to the FSM, and I know for a fact they are still available. The place that did my old gray one when I lifted it got it right, and it took them about 4 hours but it drove straight and didn't wear the tires funny at all even with 33" tires and a 3" SL.
Hell, I got tired of spending money on alignments so I just talked to mr510 and my1path, and learned to do it myself. You shim for the major adjustment, adjust the tbars to fine tune, and then set the toe.
