You guys are comparing techs to counter people at AutoZone.
Personally my local NAPA had an old guy who could find anything, if it was available. Got out the old dusty catalogs when necessary. Then he retired. Ugh
Living rural like I do now, I have one local parts store. Luckily he’s old school and pretty knowledgeable. I’ve found it best to do my own research and go into a parts store armed with my own info and part number, then give them the part number myself. Otherwise I order of the internet.
