BOBB-
Congrats! Sounds like a good news story all around.
On my repair, I put some RTV sealant/adhesive on the backside of the mirror face where it fits the ball mounting just for a little added strength.
There are a number of ways to fix this once you get the mirror out... as you found out, that's the tough part.
The really nice thing is that you can do this repair on a counter/bench top with a cold beverage at hand.. and not have dirt/oil dripping on your face while on your back under the car!
Glad information/pix helped... that's what this Forum is all about.
