What do you think it's worth?

I dont blame you maybe you could find a young guy to convert with it. My first Mopar when I turned 17 was a 66 Sport Fury with a 440. It was factory Mauve Mist Poly. My Duster is my rebound car after the break up.

That would be cool to convert a young gun. Your duster sounds like my wife. Younger, weighs less and is better looking than my first wife. LOL. Sounds like you got have a good thing going.
