Great tech tips, that is one of the reasons that I acquired so many. I was curious about the differences between the art deco years.
Now I have a question. On the 1 1/2 tons, there is a difference in the shape of the front fenders. My '41 parts truck, and my red '42 have a somewhat squared off shape as viewed from the front. My other '42 has a rounded shape to the fenders. Does anyone have any information on when that changed?
