73 Duster - how to removal rear windshield = want to reuse gasket and glass

If it's the original gasket it will probably break or crack when you try to remove it. If it's a newer gasket (less than 5 years old) then it should be possible but you'll have to be very careful. There's always a chance of cracking the glass if you don't cut the gasket...maybe someone has a secret method of getting the gasket to break loose from the glass and sheet metal. I would start by working the rubber loose from the metal using silicone spray to make it easier to slide a plastic knife/tool in between, then do the same to separate the glass from the rubber. If the rubber is old and starts to crack you would be better off cutting the gasket to make sure you save the glass.
I'm sure other members have some ideas!!
