Dodge and Chrysler of that vintage have a square dimple in the center of the fire wall,for motor clearance. I have cowls for both a 1929 Dodge and a 1931 Chryslerand they both have them and the picture does not, I think Nash as well. Rob.
It is not Mopar. The only wood in my 31 Dodge is the floor and two small parts that hold trim on the sides of the windshield. It also has wood in the top.
