Front brake Interchangeability

Hello everyone. Long time lurker, first time poster. I have a 1980 kz440 A Ltd. I was wondering what front brake calipers will fit from another kawi model or non kawi model? Maybe even caliper and rotors without getting into machining. I know what I’m doing for a MC and brake lines. Thanks

I seem to remember some old threads about this. Have you tried searching he forum?

I have but have come up empty.
