Marco, you are exactly right about the magnet sticking to the front face and not the shell.
When I bought it, it was painted black so I thought it was the proper shell. Now I know. Thank you for the information. Afordman31
I'm posting this photo of a 1931 Pick Up shell for you to discuss. It is steel, has a stainless Ford oval. Was the 1930 the exact same shell with a blue oval? Was this used on the AA as well or did all 30-31 AA trucks have the flat botton on the top face? Bob
Yes, that is exactly why it was thicker. As I noted previously, the radiator was thicker having four rows of tubes instead of three. They maintained approximately the same distance (I don't know exactly) from the fan at the rear. That means the added thickness had to go forward. This required either a thicker shell or a longer hood and they made the logical choice.
