Kz440 electronic timing advance rotor

Hi everyone!
I apologize if the topic was discussed before, but I can’t seem to find the answer.
I have a 1983 kz440D and the rotor on the electronic timing advancer is not in the best shape. I got a better looking plate, part # 1021 but I can’t find a rotor. Are any rotors from other years and bikes interchangeable? It’s the one with the pointer.
I appreciate any help! ☺️

From the cross-reference at Partzilla the same timing advancer was used on all KZ440s w electronic ignition.
You can search the full part number on EB or search by part name. Kawasaki lists it as a breaker governor.
EB sellers might use various other terms.

Thanks martin for the input. The part shows up as a full assy, I’m just wondering if the rotor can be fitted from some other model (eg 650, 750, 1100etc). The advancer plate is in good condition, the rotor with the pointer is what I’m hunting for.
