All '66 A-body, but you can also use '65 (and probably '66) C-body. The C-body arm rests semi-capture the door handle, but I like that look. You can barely see it in this pic.
'66 Dart & Valiant.
I think Barracuda had chrome plastic bases and reproductions are available. Most if not all Dart & Valiant's bases matched the vinyl door panel color.
If you don't mind a small metal ash tray in the pads the rear arm rests can be used.
Repo pads are available in black & also white, they can be painted or maybe dyed to match other colors.
Thanks for the info guys. Its amazing how much people know. The b body rest are nice to know about. I will keep those in mind. I do have the back seat arm rests. I might use those untill i get the fronts. Thanks again
