sorry, but I've been a Mopar fan for my entire life and I've never heard of a 'combat' Dodge Dart. maybe something that was exported or built in Austraila? I know they had a Dodge Charger that wasn't the same thing as OUR Charger.......so nothing would surprise me.
good luck with your search and if you find anything, pls post it here. I would be curious to see what it is......
