If you are using tire dollys, here's a pic of the cheap "alignment tool" used to set thrust angle and toe angles. I used a digital angle finder for camber and caster. These cheap Harbor Freight levels worked GREAT to make toe measurements easier. They cost $13 each ($26 for both). Well worth it to make measurements easy. Just attach the two levels with bungee cords at bottom of tire at same height (6" off the ground) and gives good reference points to measure from frame for thrust angle, then side to side for total toe angle. The tire dollies allow "movement" as you adjust.
