Drew,
We got it rolling. It turned out to be the front wheels only. The passengers side we got loose with a little elbow grease, but the drivers side was tuff. I had anointed with PB Blaster a few times and then we took the front bearing out and carefully rocked the drum back and forth until we could tap it off. The entire break system is frozen solid, so we took the shoes out of this side and put it back together. Got it under a shed for now until I make a place for it in my garage - which is a woodshop at the moment. Amazing that those old tires actually held air, except for one but the spare worked for that.
