Dino, According to Ford Performance the supplier that manufactured the rear seat delete went out of business. However, they have a new manufacturer and are supposed to be released late February or early to mid March. Part number M-6346612-B, I'm looking for one also.
Yes, it will have the X-brace and I would assume it would be either black or gray. Google the part number I posted, and it will come up on LevittownFordParts.com
