sun visor assembly ?'s

I have some questions about the sun visor assemblies on my 68 Dart.

First of all what is the correct finish for the visor mount? Mine doesn't look painted...it looks like plating of some kind, but it's a semi gloss aluminum color. Are you having them replated or is there a paint that you're using? Mine are slightly pitted so my plan was to grind out the pits with a dremel tool, fill the pits and paint.

Second, it looks like there were plastic inserts in the visor mounts where the top latches hook into. Those inserts are broken and mostly missing. Are replacements available? There is a Philips head screw down in the cavity so it looks like they should be replaceable.

Third, I'm missing the ends of the visors where they hook into the rear view mirror. Are repops available for those? If not, can I get a good close-up picture of them? Thanks
