'M'!!
I don't have a picture but if you look at the one you posted of the 1 1/2 ton--the nice shot of the grill-- head on--between the radiator and the grill, right at the bottom is a 'splash pan'. From the condition of your 'Big Bolt' that pan is most likely there. I think that is what you are looking for!!
Anyone with a picture??
