Well, those "brush guards" actually have 4 mounting points. Two on the bottom and two at the mid-spar. You are obviously missing the two brackets for the mid-spar. I have no clue where you can purchase them. However, being the DIY'er that I am, if I were in your shoes...... er, um, for the record, I would never install a brush guard, BUT, if I were so inclined, I would simply fabricate my own from aluminum strip. Shouldn't be too difficult. Long live SHROCKWORKS!
