Favorite parts store/source
I try to look my parts up online before I go to the parts store. No real counter men or woman anymore.
I lean towards NAPA, I worked for them 18 years & know their system well.
Although, NAPA isn't what it used to be.
O'reillys next on the list.
AutoZone third.
Advance auto parts if all I'm needing is car cleaning things. LOL
Last Sunday, I went to all the above, except NAPA, not one in my town.
I needed a valvecover set for my small block Mopar, no one stocked them in any grade.
I have just started to use RockAuto. Not a bad place to get parts, if you don't mind waiting.
