Neil, Below is a capture from a copy of a 1939-41 GMC Book Of Parts with the exploded view diagram of the front sheet metal and components if that may help? There are also a couple of 1940 GMC hood area pictures I snapped from a previous post by member Danielbolt from another fellow he knows that may help visualize what you are looking for.
