We only have 3 parts stores. Napa cost WAY too much. Autozone is usually always cheaper. But you NEVER buy electrical stuff from Autozone! Go to O'Reilly's. This is a grest idea. I usually(ok ALWAYS) call Chris(Webracin) when I need any kind of info. He is a genius!!! Oh, here, you never listen to the employee. They almost never know what they are talking about. You better know what you need when you go in there.
