I believe that I now have the correct fender brackets for my 1940 KC pickup.

Now, my question is what other hardware to I need to find (or make)?

I found the 1st photo on the web, labeled as '39-'40 (I am not sure of that label's accuracy).

My question is about the smaller parts in the photo. The Master Parts Catalog, group 8.142 calls for "reinforcement plate", part #350772, REINFORCEMENT, support, lower". Are these the rectangular pieces shown in the photo? I assume that if the reinforcement plate is just a piece of flat stock, I could make one myself. (Any reason not to?)

Since the holes in the brackets, the reinforcement plates and the radiator shell sheet metal are all square, is there a special square-shank bolt that holds these together?

Anything else I should know?

I should point out that the truck is still pretty much as I received it...held together by a few small bolts, some wire and some string (as is visible in the 2nd photo). Now that I have the fender brackets I hope to start test fitting things together to make sure it will all work eventually.

Thanks!
