Interior door trim strip...always chromed,or sometimes painted black?

On a low cost 1969 Dart 2 door hardtop,six cylinder,no radio,no carpet,black interior,was the above interior door trim strips (separating painted metal upper of door,and door panel)chromed,or painted black,or did you have an option of either?This might be quite an obscure question,even for mopar gurus.Thanks for any input,except for the WHATS and WTFs.
