Ha, I knew it! May not have been a 'Pro' level car but it was built by pro level people for a pro driver. Can't imagine they built it just to mess around.
Not saying I knew that but it just seems to make sense given some of the other mid-70s Mopar efforts. The level of engineering that went into some of those cars was pretty remarkable.
Very cool though, looking forward to hearing about some of the stuff they did if you are willing to divulge that info.
