I'm still partial to Oreilly's online. I can order and pick it up in store or often it's free shipping, and it's the same brand of parts I'd buy anyway. On my vintage truck I use rockauto, classicparts, etc. But mostly Oreillys online. You can hold stuff in your cart (with an account) and after two days I think it is they'll give you $10 off so you'll clear the cart.
