Humshark... I have the lamonster risers and caps... If Ringwood can't find his stock clamp.. You can have mine... just let me know your address....
I use the chrome Kury accessory clamp to mount my Zumo550 in the center of the handlebars... You can't do that with the stock clamp cause it covers up the bar... here is the mount...

So, just let me know and it's yours..
