I have a Firebird Formula that's been sitting in someone's driveway here in Florida since 1998. The wing on this car is shot and I would like to know of a source for either a replacement wing or go with a simple design that will work with the 3rd brake light. I know the OEM wing cost is high. I also know that the wing I saw on the later models was a much cleaner design.  

You have a couple choices man you have a fiberglass aftermarket on which I normally get from Brock Camaros and Firebirds in SC or Hawksthirdgenparts.com both are ebay suppliers They also offer a fourth gen style hood and spoiler and if you have a TBI motor like me the offer a ram air for the fourth gen hood
