Scott,
Thanks for the encouragement! I think this one has me whipped. I think I am
going to have to cut the head of the bolt off with an air driven cutoff
tool, or pehaps a Dremel or Foredom tool. I have both. I've been futzing
with this all day and gotten nowhere. I think my Foredom with long shaft
and skinny chuck will get down in there.
