HELP! Putting 77 KZ spoke rims on 1982 KZ1000 LTD

Hello,
I have a 1982 KZ1000 LTD that I am removing the mag wheels from and putting about 1977 spoke wheels on in their place. The 82 LTD rotors are 6 bolt units that bolt directly to the mag rim, the 77 rotors are 4 bolt, but have a wider offset (measured from outside of the right rotor to outside of the left rotor) than the 82. The 77 rotors are not in great shape, and will require me moving my calipers out to make them line up properly.
Do any of you know what rotors will bolt up to an early 4 bolt hub and the rotors line up with the 1982 calipers? My LTD 6 bolt rotors measure apx 5mm thick, 115mm outside left rotor to outside of the right rotor, and 270mm OD. My 1977 Hub measures about 68mm from the left rotor mounting surface to the right mounting surface, the 4 rotor mounting bolts measure about 78.5mm diagonaly from bolt center to bolt center (bolt circle) or 55.5mm from the center of adjacent bolt centers. So I think that the offset (base of rotor mount to top/outside surface of the disc) should be about 23.5mm
Anyone know what rotors will bolt up and line up with my calipers on the 82?
Thanks,
Montie

You may have more luck getting brackets machined to mount your calipers. As far as I know, all of the four bolt rotors are essentially the same offset and getting a cross brand rotor to fit would be rare.

Hello All,
I have partially found a fix for my problem. I found a 1981 KZ1000 CSR front rim and rotors at Union Cycle Salvage in Houston, rim was junk, but the rotors bolt onto the 77 hub, hub thickness is the same 68mm so the offset is what I need for my 82LTD. The 77 hub has a larger axle, so I need to find bearings that will fit the 77 hub, but have the same thru hole size as the 82 LTD axle, then adapt the 82 speedo drive to the 77 hub, and that should be about it.
Thanks,
Montie
