My dad and I did it this way
Removed the trim and the Lock Strip.
Slid a bondo spreader under the rubber and worked it around to free it from the glass
Took a piece of band steel (the kind they use to strap stuff to pallets/skids... real thin, tempered and flexible) and made a kinda Z shaped tool out of it.
Heated the gasket with a hair dryer and one person worked the gasket & windshield from the inside with their hands & a bondo spreader, the other person worked the gasket from the outside with a bondo spreader (using the z-shaped tool on the corners, they're stubborn)
We had the windshield out in 10 minutes, no damage to the glass or the gasket/rubber.
