I'm confused, Don. Weren't the original fasteners on a 3B "flat spring
speed nuts"? P/N FP1005?
TR4 went to FP1012/9 according to my book, but that's still what I would
call a "flat spring" nut. Same thing is listed for 4A.

FWIW, I found some "speed nuts" that have hex flats, so you can turn them
down the posts without having to cut threads separately. They have a bit of
spring to them, so can hold the badge tightly. The studs on my badge seemed
pretty soft, and the plating was rough, so I wasn't confident it would hold
machine threads. The speed nuts have worked quite well, and are removable.
(MMC calls them "push nuts")

My suggestion would be to use a small round file, and do multiple test fits,
to remove the absolute minimum metal required from the holes. Put some
touch-up paint in the holes, then use the nuts I linked to.
I've still got 98 of them in the box and not likely to ever use more than a
few. If anyone wants a couple, contact me off-list.
