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.
Well, not saying you didn't or don't know how, but proper use of that puller is paramount. I've pulled some flanges off that were in a car that had sat since the late 50s. They didn't come right off, but they came off. Tighten the spanner, strike the anvils tight with a hammer, then strike the center screw. Rinse and repeat. I've just never failed with that method, and my puller has minimal wear.
