Like an idiot I've got the same kind of thread in the diesel section; but I'll post this here too, and close out the thread.
It's out, and the new mount / bushing is in. Lot's a PB, a big hammer, and a little heat from a propane torch finally freed it up. Thanks for the help guys.

In the DIY for this procedure, somebody mentioned that you should check the capture nuts for the bracket, and they were SO right. I don't know who designed them, but they are worthless. The exit side of the nut has no threads and wont let the bolt pass. I didn't have the right tap, so I had to use the old nuts. I wish I could buy that guy a beer as he saved me an afternoon trying to get that mess apart after inevitably spinning the bolt. It was a Lemforder kit.

Also, the Myele upper control arm I had for the passenger side had the bushing about 3mm wider than the OEM. Too wide to go into the body mount. The Myele arm for the other side was correct. I don't have a press, so I couldn't try to fix it; really tiered of parts that don't fit.
