In a previous post, I mentioned the fender lamps as being a 1940 indicator. I jus took another look and see that they are aftermarket lights. The grille could have been changed sometime and replaced with one from a 1940. The instrument panel will tell the tale, they are very different. 1939 1/2 ton is series JC, 1940 1/2 ton is KC. These letters will be found on the I.D. plate.
For your sake, I hope it is a '40. '39 fenders are impossible to find.
