if you have problems with rock auto. try Summit Racing.
you can buy almost anything from summit that you can buy from rock auto. both are basically drop shippers so wherever you buy it from it ships from the same place.
the downside is navigating the catalog is MUCH MUCH harder thru summit. also shipping is sometimes slower thru summit also and no discount coupon codes.
the upside if you go over $100 shipping is free.

i order from summit whenever i can.

perception is 90% of reality
