The big three ....DORKS
I used to get calls when I worked at CSK, before they became O'Reilly, back in High School, from people asking for a Flux Capacitor.
I'd ask them what year their DMC was.
They usually answered off guard.
I'd say we have two in stock and ask if they'd like a price or a hold.
If they said yes, I'd ask them to bring the sports alminac and meet me in the alley.
Parts stores aren't the same, anymore. Autozone is a dice roll. Napa is usually ok, prefer Car Quest. Snippy old lady there couldn't get a rack for my brother's '88 Supra. She told me to come back in an hour and had it rebuilt in that time frame. Kick ***.
