Rear drum locked tight

[malford]

So, I am getting ready to move soon and was going to run my 63 down to my buddies place to store it until I get settled. The problem is that the drivers side drum brake is locked tight. I have tried hitting it with some WD, penetrating oil, whacking it with a hammer and even had a tow truck try to "break it loose". I am just about ready to break the drum with a sleadge hammer, but thought I would seek advice before I do it. Any suggestions?
