I kept trying to find a solution other than drilling because I was afraid of the effort it would be, but it turned out to be much easier than I thought. Just wear goggles.  Here's my thread with pics: Stripped motor mount bolt - HELP needed ASAP |
Same thing with a stuck rounded out inside bolt holding the door jam plates on.. a drill which just fits into that allen hole will take it out in short order and then no problem turning it... no pressure, no resistance.
