O' Reallys POS

You need to report that. That is a direct violation of O'Reilly Auto Parts company policy. "Never say no" is one of the biggest things they push. Even if it means going completely outside the O'Reilly Auto Parts chain into the aftermarket.

As you found out though, whomever it was that told you no, did not know how to look up parts correctly. I am still not used to the system myself and grab help when I need it, but one thing I don't do is tell a customer no. That's just bad business.
