Diablo, I just completely rebuilt both of my '92 full metal doors today so this is fresh in my mind. As timatoe suggested, you should probably replace all of your rubber and weather stripping. There will be 4 pieces per door/window. They are easy to take out with so.e needle nose pliers. The two pressing up against the window itself are held in by 4 brakets. The other 2 which create the channel for the window to sit in pull out and push in super easy. First, remove the vent window (pro-tip...when puting it back in, open the vent as that makes the long brace not so rigid). You said you took out the 4 screws. There is a 5th which helds that long brace down in the middle of the door. Once all 5 are out, you should be able to wiggle it out. You don't have to take the window regulator out next but I did to replace one that was frozen up and clean the other one and apply some pb blaster to free it up even more. Timato's instructions to remove the glass were exactly what I did and it was simple. You really need to remove the weather stripping at least at the top of the door frame. This will allow you access to both handles. The outside handle has two saw-blade looking keys which hold it tight against the door. You have to pull back a tab which locks the key in place befor you can knock it up with a long flathead screwdriver. When taking apart the inside handle, make sure you take the time to look at how both cables work and connect to the handle itself. This can be a little tricky but once you get the right angle it should slip into place. The new handle come with the connection points which was great because one of mine was broken and the lock never worked well. If you do end up replacing the weather stripping, make sure the one which creates the channel for the window at the vent side goes far enough down to rest on the u at the bottom of the inside of the door. You'll see this if you take out everything as I've suggested. I even did a little welding today to fix a couple of the tears in the door and connect the frame back up to the door itself. We'll see how long that novice fix. Works. Take your time and take some pictures. The last piece of advice I'd give on puting it all back together is, window regulator first, new weather stripping making the channels for the glass next, then the window vent open (this was really tight on one side and i swear I was going to break the glass but didn't the other side slid in pretty easy) then the window weather stripping and you're done.
