It's hard for me to visualize the problem you're having, and I have always just made the adjustments till I get it right. Some are easy and some can be a bear, I find aftermarket weather stripping can sometimes make it more difficult. I have heard people praise videos by this guy and he has a tutorial series on first gen glass install. Here you go and good luck. https://www.youtube.com/watch?v=_crBKY6Xl-0 I also noticed the first comment under the video gives the steps in order.
