I ended up scrapping the rusted frame on mine. Just too much damage to mess with.
Glass was shot as well. Had an auto glass outfit install new glass, with polyurethane sealant. looks and works great
As to the rubber gasket that seals the frame to the cab, I started with one from Jim Carter rubber was so hard it was impossible to install into the grooves. Ended up with Steeles Rubber - slipped in easy and very flexible. Highly recommend
