I have my dad's 1991 Trooper for a little while to try my hand at painting a car. The body's in OK shape, save for a few rust spots that need attention. One such spot is below the far rear window on the passenger side at the lower left corner, and I'll need to remove that window to cut out the cancer and replace it with new sheet metal. Can anyone give me a few hints as to how to remove that window? From the looks of it, it's pretty much pressure fit into the gasket, but I don't have a clue how to proceed. Any help would be greatly appreciated!
