I was a mechanic clear back in the 60's when things were both classy and stupid :^)
In the past few days I got in an argument with some younger gear-heads about alignment technology.
I know that many of the big shops back in the 60's and 70's had "drive-across" machines that supposedly measured toe-in as you were driving into the shop.
Of course they were actually crap, but I need to find a picture of one to prove my point. Can anyone help me?
