I'm not really sure what that piece is called or what its used for
They're called Adel clamps, and I must have installed a million of them. Used for wiring harnesses on aircraft. If you knew how much wiring is inside a modern bomber you'd be shocked. And those things are what fasten the harness to the bulkheads, stringers, etc.
I left the headlight assembly at standard height, and cut off the 'air scoop' section at the bottom. Then just flipped the lower bracket around backwards and rotated up 90 degrees, attached to a short piece of 1" aluminum angle. Fastened the aluminum angle to the fork tubes with a pair of 2 1/8" adel clamps. Used rubber grommets everywhere to reduce vibe transfer.
Total installation added another 3 or 4 ounces to the weight, and the headlight is at the standard height/attitude.
