mirror assembly

Ah the joys of lane-splitting on LA freeways... Not so joyful when the driver of a truck doesn't see you and squeezes you between him and the car next to him. Bounced between both vehicles briefly, but managed to keep the shiny side up and squeak into the clear and then off to the shoulder...

A zero speed fall over has crunched my right mirror assembly. Leaves, slope, gravel. Pride dented and recovering. Dealer will replace the unit at near $350. Mine's a 2000 in opal blue. I welcome ideas for locations of used parts or anyone parting out a 1100rt. yes, ouch. My safety...
