run out
my understanding is that both front and rear 65-82 rotors are machined as an assembly rivited to the spindles.
Therefore, you could put a dead nuts parallel and perpendicular brand new rotor on an existant spindle and get run out!
I.E., the registration face on the spindles doesn't have to be good. It's corrected by machining as an assembly.
I've had success in the past with regular sissors and brass shim stock to indicate a rotor face in. indicate, mark take apart - place shim between rotor back face and spindle front face, bolt back together, indicate, mark again, re-shim, repeat until 0.000" indicator reading.
But, a brake shop capable of machining a rotor on a car or as an assembly would be a wonderful thing to know more about.

I got a set from Muskegon Brake. Price cannot be beat. Rear rotors were right on with about .001 runout. Fronts were a little more work, at .003 and .005. But shimming with Coke can shims got them within spec.
Good luck. Ralph.
