Getting rusted drum off

[RatLabGuy]

93 Toy pickup. Tons of rust. Rear brake drums haven't been off in many years.
With some profanity and a little coersion and pounding I managed to get one off but the other oesn't even have any wiggle on the hub at all. Luckily (?) there's a section of the lower part of the rear dust cover that has rusted away so I can get to the backside of drum lip just enough to pund w/ a hammer, but no luck.
I thas holes in the face but none are threaded (or once were but have rusted away).

Any cool tricks? I need to get a new can of comrpessed air, maybe a heat-> cold shock will help?

PB Blaster or something like that. Spray it around the studs and the center bore shoulder. Then grab a hammer and smack the face of the drum between all the studs to get it to break loose from the axle flange. Heat may help.

Add to Croatians comment, I’ve always heard use a Ball on the ball peen hammer to smack between the studs.

Had to do this other day with a drum that wouldn’t move.
