Drilled or undrilled was pretty much it,z1r might have its own hole pattern B)

Wireman, I was just making comment, because the rear 78 Z1R rotors have the same bolt hole pattern, but are about a 1/4 to a 1/2 inch larger in diametor than the LTD 1000, so I ended up having to buy a 78 Z1R caliper to make things work, but the fronts wre the same size, so no issues up there....Pete

No problem,I never realized the z1r had bigger rear rotor than a kz/ltd.
Ive always tried to make sure the rear brake had less power than front to avoid locking it up,Ive even been known to file vertical grooves in rear brake pads to make it harder to lock rear wheel up. :)

you can tell these smaller rear rotors due to the fact they have 8 rivits holding the hub to rotor....not 9
