the right tool

I wish I had saved "this" because it would have made a GREAT wall display

In the late 70's --early 80's when the first body fasteners started "being metric" a then friend of mine worked for a local small dealer who had Chrysler and AMC until it fell. One Sat I got off at noon and we were "doing something" so I went down to the dealer to get him. He was finishing up putting some dealer service notes "in the book" and showed me one

It was for a late model Mopar of some kind, C barge? Noted the model, year, etc, and was alerting us that "the nut behind the steering wheel" is metric
