PS rearview mirror part number

[JEMP1003]

So... After an act of stupidity I managed to screw up my passenger side rear view mirror. All the external parts are fine, but as you can see in the video the "swivel" is broken, no resistance and vibrates while driving.

Anyone knows the part number? I've been looking at online parts stores and they only have the shell and mirrors.
