Did all mine myself also. Get your wife or girlfriend (or both)

to help. It will get them involved.
I got some good white rope that was about 3/16 in thick. I put new rubber around the glass, being mindful of the seam on the outside edge of the rubber.If you place the seam correctly, you can cover it up with the aluminum molding clip, if you are doing American Look and not Cal Look (Cal Look does not use molding.) I then pushed the rope into the inner seal that folds over the metal edge of the window opening. Leave 5-6 inches of rope hanging out towards the inside of the cab so you have enough to pull on. Put a good bit of dish washing soap on the rubber to help the seal go into place when you pull the rope through. Place the glass in the opening and have someone hold it while you get inside the car. GO SLOW. Pull a little bit through at a time while your helper is pushing on the glass from the outside. (They do not have to push with all their might!) On the windshield, have them kinda follow you with their hand pressure. You should see the seal start to roll over the lip. If a small spot does not do right, you can fix it with a flat head screwdriver (just do not poke through your headliner like I did). If a large spot (3-4 inches) does not pull through, you will probably have to start over. It can be a pain. I went with the American Look and reused my old molding. It cleaned up nice with some aluminum polish. It will be a lot easier if you go Cal Look, but not as satisfying

PS
If you do not have a new windshield, get one. They are only like $50 and make a world of difference in visibility. I got one just for that reason. Old ones have that smoke between the glass around the edges.
