A young man where I work chopped a top on an AD Chevy such as that at "Wyotech" in Laramie a few years ago. Do you have any photos? That would be a kick if it was the same one.
As far as the window, I made plexiglass ones when I chopped mine 30 years ago. I sold the cab about 10 years ago and they still looked darn good. I did it very easily, just cut them out and set them in a baking dish in the oven for about five minutes at 350 degrees and they bent into shape.
Season to your own taste.
