Michael, you might be able to find a Helicoil small enough. I
think Helicoils were designed for replacing damaged threads in engine
blocks; I know I've repaired a cross-threaded spark plug hole with one.
You rent the Helicoil installer tool from a rental place. I just don't
know how small they come.
Failing that, you might have to drill the hole to a larger size
and tap it, then install the appropriate sized threaded rod, then drill
and tap a hole in the center of the rod to accept the agraffe.
Good luck!
