You guys are lucky. At least the alignment machines you use today have some electronic accuracy to them. Back in the "olden days" we had "Bender gauges" and toe-bars. You aligned each side of the car on a tire turntable (by hand) and hoped you got it close. The "Bender gauge" read both caster & camber, and it was imperative that you knew the difference, and how one adjustment affected the other. Then, if you were satisfied with the adjustments, you set the toe with the "stick". Some machines used a string hung between the front wheels, and once in a while we were reduced to using a piece of chalk and a tape measure. But, on a positive note, we didn't have "4 wheel alignments" or freebees. Fortunately, most of the front-ends we did on the alignment rack were worn out, and that usually meant an upsell, or the customer had to be satisfied with what he got. Ah, the "good ol days."
