The holes in the backing plates do not look oversized, and I am using a

Any suggestions?

Put 'em on and use them.


Yes, I'm not sure whether they're supposed to be like that or not. The
ones that came off of there had nice large, rounded lip heads, but who
knows when they were put on or by whom, because it was long before I
ever owned the aircraft.

I just don't want to put them on and have them come flying off.
