distributor screw

[Douglas Henry <dhenry@u.washington.edu>]

Hi all:

OK, here's a small but important problem I'm having with my distributor.
My previous owner trashed the screw that holds my points in place.  I had
been able to make do for 3 years, but the threads on that one eventually
wouldn't hold the points in place with the engine running.  I found a
replacement metric screw, but it too became stripped when I applied enough
torque to hold the points in place.  I eventually ended up getting a screw
made from a harder steel that was one size up in diameter, and that worked
for a few months but it is slipping again.  

Any suggestions on a more permanent fix?  I thought about swapping the
plate from the dizzy (the piece that has the screw hole) with one from the
junkyard, or maybe a self-tapping screw?  

Thanks in advance (no distributor pun intended!)
