Go to Harbor Freight and get the tool to use. It is a handle with a bent 90 deg. blade with a cable hooked to it with a Tee handle to pull on. With the windshield trim off spray around the outside with WD-40 and spray down the blade on the tool. Insert the tool rotate 90 deg. and start to pull slowly. Don't go crunching around the glass you can crack it. You can use the wire also but I like the other tool better. Here is link you can see what I am talking about. You can probably get at auto supply also. They have the cable also.

Do the ends then the top and have someone push out and you might cut the bottom with a knife. I have taken out by myself just go slow and it will come out.
You will need lots of lacquer thinner & razor blades to clean up the window and the frame. Use pieces of wood to scrape both the glass and the metal so you don't break glass or paint. You will be shocked at how it looks at the bottom of the window frame. Might be holes in the upper cowl from water in all the crap stuck under there.
Use the 3-M rope style windshield bed when going back. They make different diameters to set the glass correct and spacers so you don't push in too far, I forget which dia. to use. You will most likely be fixing some rust before going back in with the glass. Corners of the frame rust out. Take some pics and show the group how it looks under there.
