The stock steering stem will come with a plate for the actual mount. If you have an aftermarket stem like a Lonestar you will not receive a mounting plate. However, there should be a support bracket "plate" that goes between both clamps on the front side. This keeps them from rotating. The shock and vibe clamp for the aftermarket stem installs just like an anti vibe clamp. If you are missing the bushings and washers you need to contact whoever you bought the stem from.
