Almost all my parts come from rock auto. Easy to find most parts and alternitives. Sometimes on low cost parts the shipping will bring it in line with the local parts store, but that is rare. I have saved thousands there shipping is very quick. Because of the low prices I find myself doing preventive maintenance a lot more. My mechcanic has me order parts often because I can get a lower price at Rock Auto. I feel I'm on level footing now when I got to the parts store.
