So you're standing at the parts counter.....

If I'm not mistaken Advance Auto bought out Car Quest.
A late friend used to have dirt race cars and like to experiment with engines. He built a 380 SBC in a GRT chassis and hung a "Grand Prix" body on it.
Went to the parts store for spark plugs and gave them the Autolite #.
What kind of car?
Race car.
What kind?
Late model.
Brand?
GRT
What does it say on the front?
Pontiac Grand Prix.
Okay, what engine?
380 V8
Do you mean 3800 V6?
No.
I can't sell you anything if you can't tell me what it's for.

Parts stores are requiring parts are looked up in the computer to prevent wrong parts being sold resulting in lawsuits.
My brother was in the parts biz for years and saw an Autozoner get fired for filling a customer's request for SBC plug wires without looking it up in the computer. Thats when he got out of it.
