Arm was farked ($75 for a new one), but everything else OK. I now know the inner details of the gear arm, and how it works, only another 1,000,000 pieces of the bike to go!
Next time......I know , there won't be a next time........ but next time, use the dremel to go almost through the bolt but not all the way and then slide a flat blade screw driver into the gap and give it a quick firm twist. It'll snap the last bit of the thread for you and free it up.
BTW, i finally found the arm the other night when i was cleaning up bits to sell the roadie
