Making fun of auto parts store clerks is "easy picking" and I've experienced similar conversations. With that said, I'm working on preserving a 1946 Indian Chief motorcycle, all original bike. I researched the type of modern spark plug needed to replace the ones that were in it and found I needed a Champion J6 plug. I went to the local auto parts store and gave them the plug number - "don't have any of those". "What kind of car do you have?" My response, oh, this one won't be in your system". His response, "try me". So I gave it to him and sure enough, it was in their system and they had another plug number that I had found on the net - success!
