Darik, write up a wiki entry of all the cross ref #'s and your advance stocking numbers.
That way rather than Advance Auto employees asking "What kind of car is it for?" Everyone would know what number to give you. That way, you and other Advance Auto employees won't have to hear another moped customer reply, "GO! March your ass back to where you keep the NGK plugs and bring back some that say B7HS! How fucking hard is it to read a few boxes?"
