And you have 2 options. The Oem gt500 spoiler (available on latemodelrestoration) or the 3dcarbon one. Both look good. The gt500 has the gurney flap where the 3dcafbon you can paint it to look like it has it. I think You can get it pre-painted too.
I'd do it in a heartbeat if I didn't love my backup camera so much. If it wasn't a daily driver, i'd ditch the camera!
