Loose screw in bell housing

[29FordGuy]

Well, my original Bendix threw a bolt and it is now at the bottom of the bell housing. It has for the most part laid there quietly but recently I have had a few loud clunks that sounded like it was beginning to travel around in there. I need to get it out before it does damage to the flywheel or clutch. That would not be good! I have fished from the access hole on top but no luck. I have not yet taken off the starter to see if I can access it from there. I know this has happened to others - any pointers? Thanks!
