Are FJ62 rear view mirror housings adjustable / foldable?

[IDKGiveItAShot]

I’ve googled and searched mud and checked FSM and I can’t find an answer.

I assumed the side rear view mirrors on my 89 FJ62 were adjustable / foldable - not the mirrors themselves with the electric controls - the whole silver housing.

I went to fold in the passenger side mirror and immediately heard an awful crunching sound. i can’t tell if that’s because they aren’t meant to be folded in, or because it’s old and crusty.

So, should they fold? and if they should, any thread or direction on rehabbing crunchy ones?

Yes they fold. The inner mirror is held by a plastic retainer that dissolves over the decades. At 30+ years, the mirror assembly is very fragile.
