1965 Dodge Dart Charger

OK, the washer holding the rubber hanger for the rsonator is done. They were a little tricky! But what finish were they? I'm thinking of silver cad but mostly yellow dichromated1 Ant leads?

I found a mint used bar for the front vent window frame. I just need to polish the stainless steel.

Inside the door is the rear "bracket" were the window goes up and down. It looks like it was silver cad from the beginning but what'sinside? It is glued to the metal.

Any help is appriciated.
