That kit sold. Ford discontinued the caliper mounting bracket for the rear brake kits. If younwant Ford rear discs brakes then you need to check out the bst forums for one to pop up. Then if you get the used rear kit and need to replace anything like spindles, hubs(hubs w/bearings) or calipers you can as Ford still makes those parts.
