I thought they were Mustang rotors and hubs because they were in a box that was for a '93 Mustang I had replaced rotors on several years ago (I never throw anything away). I rechecked the numbers on the box with the parts house. That's what I get for assuming. I have not been able to identify them as yet. They are 5 on 5 1/4. Not Ford, not Chevy not Chrysler. All I have to id them is the casting nubber which is BR 54 560. I haven't found a parts place that can id them from the casting number, so I guess this is a dead end.
