wrangler window replacement?

dose anyone have any tips for replacing the window glass in a hard door on a jeep wrangler?

I finailly found a set of hard doors for my jeep(93 yj), but the passanger side door was missing the window glass. the new glass was just delivered yesterday, and I'm planning on putting it in this weekend, and was wandering if anyone had any tips to make the install go a little easier?
thanks in advance,
Keith

Take the vent window out. One screw at the top of the door and one bolt behind the door panel.

thanks for the tip.
I did get the window replaced. the only isue that I had was once I got the pannel off, I noticed that the regulator arm was bent, so I had to pull it out and fix that before I could put the glass in. other than that, it went verry smoothly. pictures of the jeep can be seen here, http://www.cardomain.com/ride/2245174
