Obsolete from Ford, the 84-86 Mustang SVO and the 87-93 Saleen Mustang that used the SVO brakes have a specific Disc brake dust shield for the rear brakes. These get bent and rust out over the years. This is the SVO Specific version that does not have the holes for the ABS sensor as found on the lincoln Mark VII version. This has been media blasted and painted. It does have some light pitting evidence mostly on the inside, excellent driver quality replacement.
