Here are the directions out of my Fisher Body Manual (the GM division that engineered and assembled everything from the firewall back)
1. Remove rear view mirror from support.
2. Protect windshield glass adjacent to mirror support by placing water dampened asbestos cloth or powdered asbestos paste on inside of glass around support.
3. From inside of glass, heat mirror support with an air blower type heat gun to 250 to 350 degrees; then, carefully exert gentle sideward pressure on support with pliers until it disengages from glass.
IMPORTANT: Care must be exercised during this operation because insufficient heat will not free mirror support, and pressure on support many result in damage to glass. If excessive heat is applied, plastic laminate in windshield glass may become damaged.
4. After removal of rear view mirror support carefully scrape any remaining traces of adhesive from glass surface.
We all know asbestos products are no longer available but maybe something made out of fiberglass will work.
