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.
