Brake light switch part missing?

I think Brads is your best bet for stock look even though the originals were milk colored and most likely Brads will be black.

For the life of me I don't see how the metal ones could be installed, UNLESS they are intended to be installed from inside the shift tube and the ears ride on the steering shaft to keep it in place.
I thought the same thing. Whatever was in there is long gone now so I assume it was a plastic one and it gave out years ago. Ill have to figure something out.

Thank you for the help. Im a better painter than a googler.
