I feel a little stupid asking this, but does the upper glass push out or pull in to open? Pushing out my wiper hits and only allows the window to open a small amount. Pulling in ,I can not adjust my mirror to see out the rear.

Hi Jim I have a 1921 Canadian coupe on my car you push the top out then lift the bottom window pull it in then the top will pull in . if you try to push the top out and tighten the wing nuts the air going down the road will just push it closed. Ross
