1966 Valiant mirrors

The manual mirror that year looks like the one PistolGrib has. They also made a cable remote mirror that year. I don't remember seeing any '66 A-body with a factory RH mirror but I don't see why you couldn't install one. Just get the one that matches your LH mirror or get a matching set if you want to change over. The manual mirror fits either side....the remote one is RH and LH. If you install a remote mirror on a car that didn't come with one, you'll need to get it complete with all the mounting hardware and you'll have to drill the proper hole in the door shell to mount the control. If you're not worried about staying with the original look, get the '67-up mirror.....they're much easier to find.
