As you can testify to, that is most definitely NOT an OEM spoiler. Ebay scammers can call it whatever they want to, that don't make it so. If it's not too late, you can file a claim against the seller and get your money back through paypal. State the the listing specifically states it's an OEM part and the part you received is not. Show them the photos of it in the listing and the photos of it on your car. Ebay will rule in your favor and they can freeze the sellers paypal account unless they pay you back for that crap.
