What a jaw dropper!!! I would love to see your Dart up close and personal.
You are fortunate to have Hansens shop near by and involved in your build. I stare at Gary's work everyday on the Butch Leal /California Flash / Direct Connection B/MP HemiDuster restoration and see his craftsmanship and innovation from 1974, I can only imagine what he can do today.
Good luck with your Dart and please keep us updated.
