Originals were swedged. If the rotors have been replaced they are not swedged. It is easy to tell, if you can see the countersink and hole around the stud, they have been replaced. The swedge covers these the countersink and through hole on original rotor hubs. If yours looks like the bottom picture you are good to go. If not, they are original and swedged.
