If I am thinking of the same part you are I just got some flat steel 3/16th x 2" x the length of the bumper and then I added the bends. Once the metal was shapped I drilled holes and countersunk 1/4-20 scerws in and wielded them in.I hope this helps. You may also what to check out the two 2&1/4" pipes in your front truck for rot. They run from just behind the front bumper and go to just infront of the front beam. I had to replace mine.
If this is not clear enough I can send some pics.
