Hi, is there a specific radio installation that works for the 66 Valiant? I'd like to replace the old AM unit with an updated version with CD player. New speakers, too. Thanks in advance.

What I found on my 66 Dart is that you will need to find a unit with a "mini chassis" if you want to mount the replacement unit in the same location as the AM radio and do not want to cut the dash panel.
The other option is to mount the unit in a diferent location, like under the dash or in the trunk and use a "remote control" to control it.

Appreciate the info. It looks like the dash is pretty easy to cut, in case I needed to do that. In any case, it's a can-do situation. Thanks!
