warn-out muscle: Your coupe looks very similar to my DD business coupe. The DD model was produced in 1930 and into 1931. Have a body number or any other ID number? How about a picture of the instrument area of the dash?
dash screw on cover is missing, and no ID # tags. I do have frame, but it has been modified a little. I was told SN was on top of LF frame rail, but I do not find it. Any help would be appreciated.
