Rear window weather strip removal

Park in the hot sun. Soap and work the rubber loose inside in out. Climb in car and put feet against window and apply pressure. Gentle pressure.Not in the middle. A helper would be handy, working rubber over glass with a plastic scraper of some kind. Would help to work rubber away from the metal pinchweld too.
If edge of glass has a chip it may break. Wont know until it comes out. I pushed window out of my barracuda, rubber remained intact.
