Kz A1 rear caliper???

Have this caliper I am in the process of rebuilding. Would like to see if anyone can let me know what brake system they are a part of? I believe it is part of the A1 brake system just looking for all you experienced people to conform. Thanks in advance

Mine is from a 1978 KZ1000 Z1R, but I'm not exactly sure of every model this rear caliper came on, or for how many years this style ran to. (pic attached)

Looks just like mine. I am trying to buy a rebuild kit for mine. Due to the high cost of around $80 a kit cant really afford to guess. Thank you for your help at least I have a direction to head.

Nah sorry no this one's not for sale. I have it off for cleaning/ repad and to repaint for install on a different bike project.
