Rotor Selection, 1980 KZ750E

Are there any later-model rotors that share the odd 130mm, 7-bolt hubs on my 1980 KZ750H? I've found a few threads on the topic, but photos have been lost to Photobucket, which has made it difficult to nail down exact details.

I believe various 750-4s & the Vulcan 750s. You can check the diagrams at Kawasaki.com or power sports warehouse or some other sites.

So I stumbled on these wheels while searching the local motorcycle graveyard. They are 19” front/18” rear, with 15/17mm axle diameter, just like my 750, and have a 6-bolt rotor bolt pattern. I can’t for the life of me figure out what they’re from. Does anyone have any ideas? The rear is two-piece with the rubber damper, so I’m fairly certain they’re Kawas.

those are late 70'/ early 80's yamaha
