Windows out of a 79 J 10
Really not much to it.
After you remove the door panel, look down from the front window channel.
There are 2 screws through a bracket. Remove the screws, push the channel forward, and remove the glass. The major problem will be if the screws are rusted fast. This is what I encountered, and at that time, as per post, changed the door. I have been driving around for about 7 years with a door not the same color as the truck.
One of our local glass shops didn't know how to do the window removal, so they took the air chisel to the interior of the door and cut their way in. When they finished, they did not weld. Owner, not me, had a bit of a rattle, and the window did not go all the way up. Quite unhappy.
