1964 Dodge Dart - Wheel Stuck

It is stuck as in it will not turn. We used a lug wrench in between the studs to see if we could move it but no luck. I guess I didn't want to break the drum, so I must have been too easy on it. I will get out the dead blow hammer and try it. I still don't understand how the drum is held in place without a castle nut to hold it, seems like the wheel and drum would just come off.
The lug nuts are what hold the drum and wheel onto the axle shaft. Why not get the car back on the ground and drive it forward or backward to break the drum loose from the shoes? Are you sure you released the hand brake? :poke:
