RockAuto number? Parts problem, need help...

[Stocker]

Does anyone have a phone number for RockAuto? I can't find it on their website and would like to talk with someone there. Just got AC Delco tierod ends and drag link (or center link; I have seen it referred to both ways). It looks good but one drag link end has no threads in the hole for the zerk. I waited several days for these parts and would like a new replacement pronto; the website is less than helpful.

PS -- Anyone happen to know the thread size & count for a grease fitting? Tapping the hole might not work though, b/c the hole is shallow, and shavings could contaminate the inside.


EDIT: I finally found their number, hopefully can reach someone to help me get a replacement part more quickly than my original order.
