Restoring my MKII and my rear rotor is really rusted from sitting.
I have a set of 3 drilled original discs from a 1978 Z1R. Will they fit? The drill pattern is much nicer. With the few custom touches I have planned for the MKII this is something i would do if doable!

You can resurface them if they are within spec. ..I put 78 Z1R rotors on my 80 LTD 1000, ...no problem with the fronts, but the rear Z1R rotor was 1/8-1/4 inch bigger in circumference, & it wouldn't work with the LTD caliper, so I bought a 78 Z1R caliper to accommodate the bigger Z1R rotor, but later realized that I had enough room to file down the LTD caliper, to make it work....125.00 down the tube :(
