front drums w/o hubs?

I completely understand what the OP is trying to do LOL.

I don't recommend using a hammer to remove the drums. There is always a chance of damaging the hubs that way. When separating the hub/drum assembly on this style, the old wheel studs are usually replaced anyways. I suppose he could cut/grind the "swage" off of each stud, but it's a PITA to do.

Very few people have the equipment needed to re-swedge them together again.
