I used to work at nights at Autozone and if you go up to one of the salesman and ask to see the vendor books, you'll get a book filled with different vendors that they can order stuff from. These are major companies like Autometer, BBK, and K&N. You can get all kind of things from Headers to gas tanks. Next time anybody is in Autozone, if they're not really busy, ask to see the vendor books and check out some of the stuff that you can get.
