need a rear view mirror
 

My rear view mirror has broken, but I'm not sure which one to purchase. The day-night switch no longer works, and the whole mirror wobbles quite a bit. The end that slips onto the 'button' looks a little unusual, so I want to be sure before I order one. All mirrors that I've seen in the past slip on and use a set screw to attach.

Is it stock? Has the attachment button been replaced with something else?

Here are photos of my broken mirror:

I have an extra one for $20 shipped.
