Thanks guys! Gave everything a liberal spray of Freeze Off, soaked over night and then 3-4 good bangs on the flange with an 8lb hammer knocked them both right off.

Good news: all the pads look brand new. Drums are 8/10 but I'm going to see about having them turned. Amazed how thin those things are so I'm not sure if my local guy will turn them for me.

Bad news: Both return springs are broken. Anyone have a part # for these? Also -- one of the adjusters is broken. Looks like the wheel is welded to the nut? The wheel on one of them was just sitting in the bottom of the drum. I can't see any way to install a new one without just cleaning the bolt up and putting a little weld on there. Is that the only way? How necessary? I don't have a welder!
