The headlight bucket bolts in from inside the wheel well with four M5 or M4 screws. Before you do that, mount the headlight into the frame but make sure where the cable exits from the back of the frame, it is pointing downward. When you install the headlight, make sure the headlight is the right way up! Then plug it in, install the retaining ring and bolt it in from the rear with the four screws. On the guard, if the nose cone is off, you will see four small nuts welded to the guard. Run a tap through to make sure you don't suffer when you install the screws. Dirt makes them a mofo. Rest of it is easy.
