The RAM-B-346U base fits cleanly over your existing brake/clutch reservoir cover with the 1" ball offset. Made of die cast aluminum with an over molded rubber ball, both form and function are unsurpassed. Installation is simple and all necessary hardware is included. The mount is NOT an additional reservoir cover, but instead a plate shaped similarly to the cover that mounts above the cover using the covers screw holes and longer screws. The kit actually comes with 3 sets of screws of differing lengths. 

The center 2 slots are 2 7/16 inches center to center and are just under a 1/2 inch long.
