Thanks guys. I found the article on removing and repairing along with the following tip from Cloverleaf4:1. Position the mirror glass to give the maximum space in the UPPER corner NEAREST the car.
2. With a wide blade screwdriver GENTLY pry the glass away 1/4 inch from the mirror body at a point about an inch along the top edge of the glass from the top corner revealed in item 1.
3. Look down behind the mirror glass at the most exposed point. You should be able to see two connections to the heater mat. Just OUTBOARD of these you will see two plastic "ears" with two pieces of piano wire poking out between them. These are in fact the ends of a piano wire clip that secures the mirror glass to the operating mechanism.
4. Press down on the upper piano wire end and release it from the plastic ear. Pull up on the lower piano wire using long nose pliers or an improvised tool.
5. Remove the wide blade screwdriver and wiggle the mirror glass around to fully release the clip. With the glass free, CAREFULLY disconnect the heater. The connections break easily.
6. You can now easily access the four suicide screws and follow the rest of Bob's procedure.
To refit the glass, reinstall the piano wire onto the plastic base on the back of the glass with a smear of grease on it and secure same behind its plastic ears. The mirror is then a press fit back onto the operating mechanism.
The above procedure was driven by necessity on my car as one mirror had Phillips screws which came out, while the other mirror had #10 Torx screws, which didn't.
