Remember when every small automotive shop had an array of V=belts and serpanitine belts hanging high on a wall fetched down by an extension pole?
They weren’t depending on the local NAPA doing JIT!
Wasn’t even NAPA then......
I worked in a couple of those stores.
Even in one machine shop that still had SOME Flathead parts...but people only called for those when they got Bonneville Flats fever.
