Go to the cobreau site. Fill out the locate a dealer form. Start calling their dealers until you find one with the seat you want. I did the same when I was looking for a seat for the FFR (a mission that hasn't been accomplished yet -- big driver + tiny car = hard to find seat)

There's a shop in orlando that has most of Corbeau's race seats on their showroom floor. I don't remember the name anymore though. Real nice guy though.. even let me take the seat out to the parking lot to trial fit is.
