Does anybody have a loose rear brake rotor handy that you can measure the diameter of the center hole?

I want to buy a centering cone for the Ammco 4000 brake lathe at our auto shop class, and I don't have any rotors to measure here

I have 6 of them (doesn't everybody?). Without cleaning up the surfaces, they measured, quickly, between 89.20mm and 89.55mm.
