Oops. Broke side view mirror. What's this piece called?
 

2007 3.5L SL with all the fancy things like heated and dimming side view mirrors. I hit the dang thing with the lawn mower cyclone and broke off the black triangular piece on the outside that bolts to the actual mirror assembly. Anyone know what this is called and where to buy a replacement for passenger side (note: image is driver side)?

See the red circle for what I'm referring to: https://i.imgur.com/Jiz9OkI.png

It's called "junk yard".

Dang, I just threw one away.

My dad got a used mirror and I swapped over the whole thing. You'd have to de-pin the wiring to pull it through. There are dozens of wires, I thought about it myself but it's really not worth it.

I was planning to just cut the wiring in half and then splice it back together or something
