How wide is the rear window

Does anyone have a solid back glass outside of their truck that can tell me the width at the widest point? I have something in mind I would like to try but I need to know exactly how wide it is first. Thanks

Top corner to top corner about 40 inches

Bottom corner to bottom corner bout 50 inches

Top to bottom sides about 14 inches.

Thank you very much Dan. Looks like it's a little bit wider than the piece I can get my hands on, which is what I was worried about.

What were u gonna try?

I was going to try to make a custom rear window, don't want to spill too many details. I'm back at the drawing board, may just go for some of the crazy 90's style tint jobs instead... not sure yet.

Oh i see. Well that sounds cool.
