hi can anyone help, i bought a touratech mount for the zumo 550 from the NEC show and im sure the sales person said it would fit a 08 1200 gsa, when it arrived i noticed the clamps were to small for mounting on the top bar which secures the screen, i did ask if it would fit there and i was told it would, does anyone know if you can get the larger clamps for it to fit? any help will be most welcome
