1970 Dart swinger Door lock knobs question

I have a 1970 Dart Swinger 340 with a black interior, Someone decades ago changed the door lock knobs (interior) and I want to replace them with original style. My questions are as follows
. were they chrome or black to match the interior?
. did they come with gaskets (ferrels) on the door to guide the knoobs?

Also anyone know where to buy them?

THANKS
