My mirror set up uses the bases off of the common cbr style after market mirrors, I'm pretty sure they are Lockhart Phillips.

Look similar to this - CBR600F4/F41/929/RC51 Mirror - Chaparral Motorsports

Anyways, one of the two mounting bolts snapped in half while I was over-tightening it.. So rather than buying an entire set of mirrors just for one base, hopefully someone has one or two laying around that they would like to sell or donate.

Thanks, James
