I have a set of new Arizen Racing seats. They look like the pic below except mine have black suede in the middle, not full leather. They are new /never been installed but been sitting in my shop over a year now. They need to be dusted. These are also the wider version. They come complete with sliders and I will throw in a rear seat delete from http://rearseatdelete.com/mustangcoupe.html
Its made from plastic (not wood) and I changed the carpet to match the interior on the front and the truck on the rear. This has never been installed as well.

$1250

Seats are custom order and you could pay what I am asking for just the seats alone.
