Please be patient as we answer questions in the order in which they are received. Please read the listing carefully. Also, we do not know your specific individual vehicle, so you will need to consult a dealer or service manual for questions about your specific individual vehicle. For shipping information, eBay lists tracking information automatically, so we cannot tell you any more than the order page will display automatically anyway, so please do not ask shipping questions unless your order has not shipped as agreed, which should not happen because we ship as agreed with eBay. For example, if you order a 3 business days handling time item on the weekend, it counts as a Monday order, which means it must ship by Thursday (the third business day after the day the order was placed) at midnight, according to eBay; please do not message us on Tuesday asking where your item is when it is not scheduled to ship until Thursday, something you agreed to when you ordered the item. For technical matters, you should contact the manufacturer's technical support department directly, as we will just refer you to them anyway, so asking us technical questions is not a good use of your or our time.
