Thanks for posting the picture. The picture does not show the "two-eyed" rod used in 38/9, but if you check the parts book, they carry a different part number. I believe the 40 used the bracket mounted on the side of the bed. I know a friend of mine and I had to cut one off of a 40 bed to load the bed into a van. The pictures in the Green Bible are "typical" pictures and do not show all model year changes. If you look at the picture you posted, there is another obvious error on the picture. It shows the year range of 36-41 for the spare mount, but pictures the wide-five flange. The 40 and 41 did not use the wide five.
