So I got this link from BAZ and it has been a tremendous help.

Also Colbino was nice enough to answer my questions and give me some guidance. I have one fully done and as good as I could get it. One left to do lets see how this one goes. The outer rubber from Datsport was a breeze in comparison to the frame to glass seal.
Here's some tips from Colbino
Hey Vince,
Its been awhile since I did that super annoying task! Let me see what I can recall.
The first window I did went in easier then the second one. I made sure to do it on a cool day to minimize the rubber expansion. I even placed it in the freezer while I was prepping my work area and the frame.
Make sure you have the correct length bracket screws (still available from nissan) so that you don't have them sticking out too far and interfering with the seal.
Double check your inner lip is perfectly smooth and free of any old paint or dried weatherstripping so the seal can slide freely along the track.
Before you start the job put the meal end pieces on the frame and verify that you can freely screw them into the rest of the frame. I tried each one in both frames and one fit better then the other. This may not make any difference in your case, but after dealing with the annoying task of getting the seal in you'll want to make sure that the last part of getting the back piece in, lined up and screwed on doesn't end in you having to start over because you cannot get the holes to line up. It happened to be several times.
I put my bracket on and cinched it down and then lubed up everything really well. I made sure every area of the channel was slippery. Try not to get any excess on the outside where you're holding the frame so it doesn't slip around.
I then lubed started with the far bottom corner and showed it in there as far as I could. Then start laying the rest of the seal while constantly pushing the seal towards the starting point. The seal feels like it's a bit too long, which it may be or it just stretches over time. Not sure. Either way your goal is to keep the seal from stretching out.
Now you will want to lube up the inner channel where the glass will slide into. If you have a buddy it will make things easier as he can help pull the frame apart while you slide the glass into the seal. Once the glass is it you will probably have to start "walking" the seal back towards the far lower corner that you started with. Your goal is to remove as much of teh seal slack as you can so that you can get the back metal piece on and finish the install. If you have a rubber mallet you can tap the end of the glass into the seal. Also, a plastic paint scraper or some sort of rounded piece of hard plastic will help you push the seal towards the corner - push down on the rubber and slide towards the starting corner; about 6mm at a time. Take your time and do this to everywhere along the seal and always going towards the corner. The upper curve is where I had a gap and needed to always work on. Towards the end I would put the end of the glass on my stomach and pull the frame towards me just to get the glass to slide into the seal that last half of an inch. It's a messy job, and over time you'll want to spray some more lube if it starts to dry. I actually think dawn may work well too with this process. You can also use wd40 as it's not going to harm the rubber.
