I have some Ram mounts that came with my Zumo that I do not need, as I purchased a BMW mount.
They are #RAM_B_202U 2 7/16 base & 1" ball
#RAM_B_309 clutch brake, ubolt combo kit
#RAM_B_U-A dbl socket arm.
Just pay for shipping ( probably less that 6 or 7 dollars. The weigh about 2lbs for all 3 pieces.
