Thanks for all the replies, guys! At this point I'm gonna make some calls this morning and see if I can have someone remove it for me. I hate to go that route, but I've wasted enough time on this already and I'm done.

If nobody can or wants to remove it for me, I"ll try to use Bodhi's method. Or inserting a rod through the hole I drilled and then driving wedges between them (one on either side) to see if that will get it out.

Also, I'll just apply as much heat to it as I can at this point...
