3d Carbon has a nice rear spoiler (and window spoiler). Street Scene also has one. I think I've seen both on ebay but just Google 3d Carbon and Street Scene and you'll find places to compare prices. Seems like a also saw a website where they will paint it for extra $$, but that saves you from finding a local shop. I've also seen the "wing" type spoiler, but I don't think they look good (esp on a Fusion).
