A shot in the dark, for sure. A lot of tin gets swapped around over the years, and that sure looks like a '60's-70's paint job, but if it were the Dahm Brothers car, that would be a stunning find.
What else do you know about it? According to some posts on the H.A.M.B., the Dahm Brothers car was set up with a Chevy frame. Can you tell what kind of frame this thing was set up with?
