Yes Iam putting the window in first. The drivers side went in easy, first I used some foam rubber i had and centered the window in the door frame then i started the vent frame in the door, lining up the channel with the window. Keeping the window in the vent channel and the rest just fell in place. Boy, just lucky. Now i may have to pull it out again because the vent window handle came off. anyone have a fix so i don't have to pull it again? 53 3100 root
