Where to buy a Medusa ROTOR?

Hay suicideniel, Iv'e had the same problum on my medusa 36-60-3100.It pushed the end bell off and destroyed the can bearing.as well as rubbing the coating off the rotor.on my motor atleast the bearings are 5x10x4 /1/8 clutch bearings and they pushed out fairly easily and tapped in even easier.I was worried about the coating but on my rotor but i think its just epoxy so i replaced both bearings and got one of Mikes motor mount heat cync/clamps put it all back togther and its been running for three weeks maybe 300 laps and all under 115 deg , for what ever thats worth. good luck and happy 4th!
