How rare?

In 1966 when I was in high school, I had a friend who owned a 1965 Valiant V200. It was a red four door with a red bench seat interior. It had power steering and limited other options. What I always thought was unusual was the Commando 273 and four speed that was factory installed. His dad sold the car when he went to Viet Nam in 1968. Has anyone ever seen a combination like this? It was a fun car. Wish I had a photo of it.
Near the end of model year run they put some weird combos out the door
