Does anyone know the size specifications of the metal spacer in the Mitsubishi Alternator that's used in Ford AUII?

I lost the spacer some this morning, it was in my pocket, must have had a hole and spacer is no longer.

Other question is where would this metal spacer sit / located at. I should have taken a photo before removing the stator.

There is nothing that shows an exploded view of the alternator in any of the workshop manuals I have.

Found it, It was near the wire wheel brush ready to clean (forgot I placed it there).

I do have a question , hopefully someone might know.

What type / brand of 2 armed pully is best to remove the small bearing?

I tried using Google , not very specific, workshop manual says bugger all.
