I'm another one that votes for getting a caster/camber gauge from Longacre as well as their toe plates. I made my turn plates out of a few pieces of 14 ga. steel from the local metal place. I have aligned at least 30 cars and even had a few of them double checked on the alignment rack with no issues. Someday I'll have a drive on lift and it will be even easier!

If you want links to the tools let me know and I'll look up the part numbers. One important thing to consider is that some stock spindles will need a little grinding to let the caster/camber gauge sit flush on the drum or disc. You might be more comfortable with one of the units that mounts on the wheel.
