I did for my 66, replated the pivits zinc & painted the linkage bare steel. I used large heat shrink to replace the plastic on the pivots, worked great & looks original.

The heat shrink also works great for making the black plastic where the antenna mast screws in look like new, mine had marks from pliers or vise grips.

I had to make new ones, used some roofing sheet rubber, thickness was the same.

I found a pic of the linkage under the dash (hope this works):

Yes, they look like little thermostat gaskets.
