Replacing SBP Rotors

Can anybody tell me what's involved in replacing the rotors on the early, SBP hubs? Is there a thread that covers it? I am buying a set of early brakes to put on my car & will probably replace the rotors at the same time. Does it just take a press (I have one), or is there something else I should know? I have a FSM for my car, but it's a '64 & they weren't available then, so it only covers 9" drums. I also have one of the Chiltons Professional hardbound manuals for '72 through '78, plus a lot of general info manuals but none of them mention rotor replacement. Thanks!
