The silver ones holds the hinge at the top in and the brass ones hold the rubber seal in place. The silver ones are brads and you put the washer over them and flatten it down. Just did mine and it works well. Have to make some spacers for the tension spring for mine, there were none on mine and window blows shut. Al
If it was easy, women and children would be doing it. Al
In my 47 coupe the rear quarter windows blow shut and there doesn't appear to be any resistance. Should there be some tension springs there too?
If you can find one use a rivet squeezer. Maybe find one you can borrow around an Air Craft repair place. I had a friend that was a pilot and he had one I borrowed.
