Auction is for one pair of NOS GM Wheel Well, and Trunk Side Plugs. These are for the 3/4" hole that is in the wheel well area, and along the trunk side, right behind the rear tires. There is a small groove area under where these plugs go that was supposed to allow water to drain out of the trunk area, if water got in, but usually plugged up with road grime. People would pop these out, and toss them away so they are usually missing. The ebay fitment guide is only a guide, and sometimes wrong, so please make sure that you have a 3/4" hole, and these will work. When only GM works, these are for you. I received these from a GM dealer several to a box, so you will NOT receive the box. Winning bidder to add $4.50 shipping with tracking. US only, Paypal only. Thank you for looking, and good luck!
