Corbeau seats may be purchased seperately. The Forza comes in two different sizes. Standard, about 21 inches at the shoulder and a little wider. Bases need to be purchased for a direct fit to the floor mounts. I recently purchased two for my 70 240z. Its a close fit, at the shoulder, when closing the door with the seats all the way to the rear.
I used 15/16 grade eight bolts for the front mounts and 3/8 at the rear. The seats are best installed by attaching the BASES to the floor first then attaching the seats to the bases.
The seats are "deep" but with helmet there is no roof contact. I'm six feet tall. Be prepared to take your time getting in an out, not ....for folks with lower back issues....oh, well.
