I am looking for a black factory deck fin for a 2004 LS. Most of the ones I see on spoilers4less are like $200. That seems like a lot of money to pay for a piece of plastic. Does anyone know how much you would pay at a dealer? Also, I've seen some on ebay for like $70, are they good or are they just that cheap cause they aren't painted? If anyone has one of these fins let me know where you got it from and how much you paid. Thanks alot.
