[Healeys] BJ8 Door Lock Plate R&R

[Mike Garvey]

The door lock plate (Moss terms) on my BJ8 needs work: the round pin is worn
and loose on its mount.  I can buy a replacement lock plate; my question has
to do with the anatomy of the fasteners inside what I think is called the
"shut pillar".  Before I remove the screws that hold the lock plate on, I
want to be sure that they don't fall into some deep crevice.
Advice welcome..
Thanks, Mike
