Where can I get a right side west coast moto-mirror

I have an 05 Peterbilt 379. It has the 6X16 moto-mirrors with the spot mirror built in as opposed to mounting underneath the big mirror. It is heated and motorized. The glass is cracked. Does anyone know if the glass can be replaced or if I will have to replace the whole mirror. Also, Does anyone have one of these they would sell? Perhaps from a wrecked truck or something? Where do you find these mirrors? I have looked online and can only find non-motorized mirrors. My mirror looks like this:

 

For what it's worth, you can order just the glass but you better be sitting down when ASK how much it costs.
