I built one of these a couple months ago but havent had the time to finish it. I just bought a piece of 1/8" flat steel for $4 and bent it to fit. Except I ran the piece of steel to mount under all 4 mounting bolts under the p-pad and then it bends up and and around for the back pad. Ill have to slip some pics in here of it, I was just waiting to get time to finish it completely before I posted.
