Above are two pictures of the 122" Wheelbase Ford Straightside Pickups, as illustrated in the Australian Ford Sales Brochures for 1940 and 1941. You will see that the full length side trim is the "carry-over" three Ribs from the 1938 and 1939 Australian Ford models.
Unfortunately, a lot of people can't tell the differences between 1940 and 1941 Ford Pick-Ups - Trucks. If you study the above two pictures you can see slight differences in the Hood and Grille.
In the real world of 1940, all Ford Pick-Ups and Trucks came with the standard V8 Engine. So, a prominent V8 insignia was pressed in to each side of the Hoods just in front of the Vents. (see top photo) When the 1941 Ford Pick-Ups and Trucks were released, a brand new 6 Cylinder Engine was an option for the first time. Rather than having two different Hoods, Ford chose to just offer one and removed the V8 Pressings on the Hoods.
In addition to the deleted V8 Pressings from each side of the Hoods, the 1941 Ford Pick-Ups and Trucks also had slightly different Trim on the Hood and Grilles. I will add details of the differences in the Grilles in another Post.
