I will post some photos of my parts later tonight. I have two examples with the cut outs...a little different, but they are present.

I don't know if this response is helpful to what you are doing, but I have two of those parts that came with my FrankenProject. My cab, grill and fenders are 1940 Chevrolet, and the part you are making looks to be mostly the same as the parts I have.

The first two photos are of a part that came with my project, and the second two show a part from a second source and the part that it was screwed to when I received - still showing with the primer paint outline showing the location of those cut out areas relative to where it mounts.
