I’m working with a 66 Plymouth Barracuda and my question is the panel below the trunk and between the taillights is that panel the same between the 66 barracuda and a 66 valiant?
You'll probably notice that the section where the taillight bolts to the quarter panel is slightly different on the Valiant. For use with a Barracuda taillight, you need to remove that small welded-in piece where the backup light goes.
