Your welcome. Rotor has H 50137 and a symbol that looks like a cross between an F and a T. I do not own them and they will probably wind up on ebay. They are not bad, but are below minimum. Hub is good, but that register size is smaller than the b body types.

I am a B body guy with a 69 and 70 Disc Brake car, so I was scavenging for those parts. You where on the post in the B Body Forum helping a guy overseas with a single piece rotor on his car. Not sure if you saw what I added. I have broken down KH and Bendix rotors and compared Hubs.
