Now that the windshield is so clear, I got tired of looking at the degraded mirror glass on the rear view mirror and decided to do something about. After reading a variety of threads, I found that he best way to remove the glass was to soak the mirror in very hot water for 15 minutes. By then, the plastic/rubber gasket is semi-pliable.
I used my thumb and was able to work my way around the gasket several times, each time prying a little further so as not to crack the glass since it is glued to the backing of the gasket. Eventually, I was able to get the edge of a plastic decal applicator squeegee under the lip and gradually moved it around the perimeter, each time pushing a little farther in. Every few minutes I would soak it back in the hot water. This worked great. The glass just popped out.
I was checking on prices for resilvering the existing glass but found that Paragon Corvettes sells the new mirror glass for 67-73 GM cars for $40 which is comparable to resilvering the old one. It is due to arrive tomorrow and we will see how it fits.

Here is the original 1972 black pebble grained mirror.
After the glass was removed. The white is the residue where the glue pulled off the silvering from the rear of the mirror:
The only logo I could find on the mirror was a "GM" at the top of the gasket:
Nothing at the bottom:
