If some kind soul has their intact or nearly intact glass out they might be able to trace it and send that to you.
I had pretty good luck taking the pieces of my window in and having them use that as a guide. If it's not absolutely shattered, you may be able to piece together what you have and make your own.
Then you could cut a piece of cardboard, masonite or thin plywood off it for a test fit and slide it into the window channel, adjusting as necessary until you're happy with the fit.
If you have no glass at all, you might be able to trace the window opening, add a little at the top 3 sides for the window channel and test fit your mock up as above. With the window rolled up, you should be able to stick a ruler down into the door to gauge how much length you need.
That's how I'd tackle it anyway.
"How the heck did that happen?"
