Just what I needed.
Me being the dum person I am, I didn't see that these didn't come in a pair so I had to order the other one separately. They worked exactly like I needed with the mirrors I ordered. I was able to swap out the crappy aftermarket ones so I can see again!
This was just what I needed to install my new smc mirrors. They are the same as stock with different threads to fit smc mirrors on my 690 enduro r.
