We are a Internet Dealer that buys & ships product as ordered, we do not stock

returns or cancelations on parts orders. When we place your order, there may be a
possibility that an item(s) will be out of stock or on backorder at that time. You
can cancel that particular item if you don't want to wait for it's release, and get a
refund on that item only. We do not exchange parts that were ordered wrong by you,
so make shure you have the correct model & year when placing orders.
