Stuck gas cap

[Beachwood]

I was wondering if anyone have ever heard of a gas cap getting stuck on an airhead? I have a 1984 R100 RS, which due to me being unable to ride it for about a year the gas went bad. When I went to drain the fuel I found that I could still unlock the gas cap but when I tried to turn it to remove it I found that it would not come off easily. I applied a little more force and then I heard the dreaded sound of the pins snapping. So know when I turn it, it just goes "pop pop pop". Does anyone know how one goes about getting this thing off now. Also does anyone make a plain gas cap with no lock on? Any help on this subject would be greatly appreciated.
Thanks
