how to remove rear view mirror on a 95 taurus?

I know this sounds stupid but can someone please help me.I am a gm guy and am use to a set screw.This one has a small slot I cant see if there is a scwew up there or not.:uhoh:

Hmmm, I believe the '95 Taurus rear view mirror would have a set screw such as you are familiar with. I don't recall what size hex key it takes though.

Maybe someone with a '95 will take a look at theirs and correct me if I'm wrong (wouldn't be the first time).

Definitely should be a setscrew up there, I've had mine off and don't remember the size either.
