I think I might try this, I could either weld a bolt head or weld my rough
homemade 9mm allen wrench to what is left of the head of the original allen
bolt.  I have access to a gas welder so this just might work.  I was using
a allen type socket wrench but as soon as I would torque the bolt the
wrench would loose its grip and pop out.  The allen bolt is pretty deformed
from all my attempts.  I just hope that I can get a good enough weld to
torque on the bolt to get it out.

Thanks for the suggestion.
