Kelsey-Hayes Hub to Rotor

I've used that on 2 cars, a 62 and a 64.
One side of my 64 the drum was destroyed, it would not come off, puller, heat, bfh, nothing worked. Someone suggested I put it back together with the nut loose and drive around. I wouldn't do that, but it didn't run at the time and the drum was already deformed.
Took 8 hours to get off, and the pop it made was a sound I've never heard.
