My apologies to JordanVW... You were right.
The interior rear view mirror you sent me WAS interchangeable with mine.
My mechanic finally got it on for me today. (That didn't come out quite
right...)
I guess replacing the mirror isn't the reverse process of removing it.
You twist the stalk of the mirror right to left to remove it, and right to
left to replace it too... And you have to take the actual mirror part off the
stalk to replace it, then put the mirror back on the stalk.
Thanks Chris. The mirror is lovely.
