Flip that half of the bracket upside down? Pretty sure the half with the mirror posts is a half-circle.They sure look like quality mirrors. but the V has the threaded inserts which will have to be drilled out. I've been looking for a replacement thanks for the link. The only thing is what to do with the original posts that stick up off the controls when you take the stock mirrors off. A flagholder perhaps?
I did my own home-grown bar ends with the stockers. It works really well and I am happy. here's the link on how I did it if you're interested.http://www.kawasakiversys.com/forums/showthread.php?t=6677&highlight=mirror+modification
