I have an ST Coupe and someone got this spoiler for me thinking it would fit my car. Later I got a trunk lid with spoiler for my Celica. This spoiler has the outer two posts on a slight angle to fit the curved edges of the hatchback. I don't know all the models this might fit, but I included a link to lots of pictures and I can measure anything needed. I have seen this exact spoiler on a hatchback. I don't know if it was a GT or not. I just want to be clear with the buyer because when I bought it the seller said it was for the trunk of a coupe when it obviously was not.

The condition is good. It's all black. The underside shines up to a really nice gloss. The top surface had oxidation and some water spots and a few scratches. I went over it with cleaner, polish and wax quickly and it shines up and the imperfections only show up when you look really close.
