I'm going to throw 2 ideas at you. I came up with them during a discussion about late model rats. If you chop it and have to deal with the front glass anyhow...
Cut the cab front to back, except the rear wall, and pinch the front in 4"-8", to angle the sides in toward the grille like a 30's cab does. Yeah, it would be some work, and I don't know if a cut down the center or 2 cuts on the sides would be needed. Also change the cowl and roof so you can use a flat glass, split (with a post down the center) windshield.
Just some ideas for you to chew on....
