Reply to "Vent Window Installation"

Lube up whole front and bottom edge, put glass in and slide it in. Front edge should go all the way to the front of the channel. I used a rubber hammer and bumped it all the way until seated, I used the hammer on the glass, not on the thin strip of rubber that goes on the back of the window. Insert the rubber into the chrome divider and massage it all together to where it all fits together and put in top screw and bottom bolt.
Push the divider bar as far forward as you can before tightening down screw and bolt. You also might want to put side glass in the door before putting the divider bar on the car, much easier to get in with it not installed.
Good luck.
