The fairing brackets on the main wheels bolt to the inside of the collar that the brake bracket also bolts to. There is also a small fairing bracket that screws into the axle nut on the outside, but I won't put that in place until it's time to install the fairings. The brakes attachment is a little strange - the main body doesn't actually mount solidly to anything. The body has two pins that slide into the attach bracket and allow the body to move in and out. With the body in place, I slid the outside shoe in and bolted it in place. The sliding pins and the brake shoes are all that hold the whole assembly on the wheel.
