Elks, probably not a lot of that stuff available in your area, but if you get into Denver, bring your tools and go to Western Auto Salvage or Pull n Save. Find what you want and remove yourself.
Got $350 worth of parts for the wifes blazer at Western Auto Salvage for 22 bucks! Didn't take much longer than a trip to the parts store!
If you look them up in the phone book they can tell you what is on the lot at that time but they change hulks out constantly. They will hold something for you for a short while too.
