- Each bar will require drilling a hole to fit the support and retainer bolt between the support upright clamp and the bar. To do this ideally it is recommended to use a drill press to stabilize the bar to create a clean hole without burrs.
Bars do not come with additional mounting hardware. Typically, an M6 bolt is used at the base to secure this bar to the seat support clamp, and M8 seat mounting hardware are used on the top to secure this part to the seat.
