Seized Drum Brake

Rear passenger drum brake (9") is stuck. Trying to get the drum off but having a hell of a time. I got it loose from the backing plate, so it appears it's the shoes keeping it in place. Per the FSM I took two little screwdrivers through the access hole on the back in order to loosen/release the shoes. I can get the first screwdriver on the adjuster lever to get it off the star wheel, but for the life of me I cannot get the star wheel to move in either direction with the other screwdriver.

How easily should the star wheel move? Due to the nearby spring shackles I've got a nice collection of bloody knuckles. I sprayed a ****-ton (technical automotive term) of PB blaster on it. Anyone have any ideas? If I'm missing something, please let me know. This is my first foray into drum brakes so I'm open to input. You can call me Drum Brake Grasshoppa.

Car is a 68 Valiant. Parking brake was off. If my continued PB blaster attacks don't loosen it up, do I have a fall-back position to get this drum off?
