Tried to go to the dealer for parts
I have to say that I've had REALLY poor luck with dealers anything, "back in the day." We never spoke the same language. This was years before I sold parts. Mopar calls the clutch gear / input shaft in a 4 speed a pinion, example. When you've been reading GM / Borg Warner / Ferd catalogs, this makes no sense when somebody throws that at you. "No, I'm not working on the rear axle!!!!"
And, When I had that 70, EVERYTHING seemed to be "in a different language." It didn't matter whether I told them I had a Dana or Spicer, nothing seemed to compute. It took me a long time to figure out that it also was the same thing as a "9 3/4" I was on Mars, they were on Venus. The car could be parked right there in front of their great big window, it didn't matter. Hell they could be LOOKING at it. Some of those guys acted like, not only had they not only had not every HEARD of a Road Runner, but that they WISHED they COULD NOT have NOT EVER heard of one, or maybe wished it had been made by someone else. It was as if the damn thing was a dirty word to some of them. It was unbelieveable.
