Oddball 1970 Dart GT Find....

Interesting find. I see it has no console in it, as it was equipped with a column shift. The police car theory sounds appropriate, especially in light of the roof reinforcement option which could have been meant to support the added weight of a bar light or dome roof light.
Mine is a Dart GT as well, but a '71. Bruce would have been tickled to see this one, thanks for the post.
