1967 barracuda brake rotors help

I have a 1967 barracuda that has disc brakes on the front and I need to replace the rotors. Not sure what came on it originally but when I got the car it had Kelsey Hayes calipers that were siezed and warped rotors. I put ssbc calipers part # a199-1 and bolted right up and looks and works great but now I am having trouble finding rotors. I've done a lot of research and coming up short. I know it has 5 on 4 bolt pattern. Driver's side has left hand threads and passenger has normal right handed threads. I believe they are 11inch rotors. Is the hub and rotor all one piece? Can anyone please point me in the right direction as to what I'm looking for?
