This is an adapter that allows seat rails for semi-bucket seats to be used with full bucket seats. It appears to be compatible with Recaro, Bride, and other brands. The item is as shown in the photos. Only one set is available. The condition is unused as shown in the photos, but please assume there may be some storage scratches. I am also selling genuine Recaro seat rails for CT9A, so please take a look if you're interested. Thank you for viewing.
