I wonder if the supports are rotted out? I don't know how long the windshield leaked before I got the truck and put the new seals and glass in. next question then is what to do to fix it. wonder if I need to find a rust free cab and turn it into a project truck and not a daily driver. maybe time to get that 379 ive been looking at. I love my c.o.e but its becoming more of a pain now that ive been driving it every day.
Kind of way old trucks are,ran 84model,had to put fan over top of defrost vent blowing on windshield for best result.as for glass moving that's not good. Kw where known for cracked tunnel.
look at ft. lower cab around pin that cab moves when its jacked up, if still good it ok to start drill and replace riv.its all around.
