I have a set of mag wheels that came on my 69 Mustang. From my research I believe that they are Appliance brand. The center caps have the AP logo whereas my research shows appliance wheels had an A only. Perhaps someone could help me identify these wheels for sure.
Those are Appliance. The shape of the outer lip where it transitions to the spoke area is a clue. Look on the back and see if there's any casting numbers or letters. True American Racing wheels say "American Racing" while lots of other wheels have nothing. Oddly enough some Appliance wheels had "Made In USA" while others I've owned had "Made In Japan" cast in them.
