I just did this on my door resto and it's ^ pretty much that. When do this process, do it with the window top OUT of the door.
1. Clean all metal threads with a wire brush.
2. Clean the rubber.
3. Install the rubber using a screwdriver. Be gentle and don't slip and pierce your hand like I did. Push into the corners well.
4. If it splits and you can't afford new ones, silastic will fill the gaps.
5. Drop the pin into the hole, ensuring you go through the swing-stopper thing. It can go in four ways, so just mess with it til you get it right. It's designed to prevent the window swinging forward too much.
6. After you've dropped the pin through the swing-stopper, go through the plastic washer as above.
7. Now it's time to bolt on the chrome head to the top of the door frame. Two long skinny bolts. Not too tight, just enough so the window doesn't move around whilst you're trying to put the last of the fasteners on.
8. Back to the bottom. Big washer, spring, little washer, big nut, little nut. Tighten just so you get tension on the spring.
9. Now you're ready to drop the window top into the door. Easy now, the paint is fresh.
10. Open the wing window almost all the way. Now.
11. Drop the window top into the door. It should drop home. Don't forget to keep the retaining tabs on the right side of the door or you'll mess up your new paint.
12. Bolt the window top in. Don't forget to bolt in the bracket that stops the window from falling to the bottom of the door. Two little short bolts at the bottom of the door.
13. Bolt the rest of the bolts/screws in.
14. Hang the door. Actually, hind sight tells me if you can do this first then steps 1-13 would be a hell of a lot easier..
