My problem was solved a while back. benzerhead116 now has a slightly different problem from the original. Check here for more info on ignition switches. Be advised the threads are now crossing multiple models, so specific techniques may vary. In the first link there's a reference to a locksmith template that lets them drill the collar on the 'single hole versions' and you can remove it easily. That's in addition to the other techniques, using sanders, voodoo dolls, etc.

There's also a good how-to here: http://www.peachparts.com/shopforum/showthread.php?t=260981

The above link has pics of some of the parts that broke on mine. The other part that's held in by the hose clamp is the actual ignition switch housing under the dash.

That's still in mine, still with the hose clamp. I'll get around to it someday.
