Never know til ya try. Call em and explain the situation, the worst that happens is they do, in fact, tell you to piss off. But they might not...

Had a set of rotors for my truck that sat here for over a year before I realized the guy gave me the wrong set. Took em back to NAPA, the looked to make sure I didn't use them (like I could have?), and promptly gave me my set that was STILL sitting in their inventory. And they gave me money back for screwing it up.

Just never know.
