Does anyone know if the Wilwood discbrake hubs have their partnumber stamped on them somewhere?

I'm trying to figure out with some websites what kinda parts the Wilwood discbrake system consists of on my '57 Chrysler.
I've measured the current rotor to be 11.75" / 1.25" thick vented rotors, and also have the 120-4952 calipers. But I can't find any hub-specs online that would fit these 2 parts. I would like to duplicate this system onto another car.
