Hi, all OP again. My internet connection went out, so did not get to
check this until after I went back...My mom, of all people suggested
wooden matchsticks in the holes.

So, I ground off a small amount of the striker plate thing, the part
when a piece folds into the hole itself, stuck matchsticks in and
tightened it down. May not be Bob Villa approved, but it worked.

Thanks again for the suggestions.
