I measured on the axle flange. The rotor does sit flush to the flange. That's a good thing to remember when doing a rear brake conversion though. I have no way to measure run out on the rotor itself unless I move it to the other axle.

Basically, what I did was work my way back from the wobbling wheel to either where the wobble ended or to where I had nothing left to remove. That turned out to be the axle flange.

Thanks!
