Sort of like winning a lottery:
You will be waiting for a long time to find a "donor" window of the same size. The next option is finding one with a frame that can be cut down to size.
You might luck out and find someone that can make you a new one but be forewarned its going to be be $$$.
Replacing the plexiglass with tempered glass is your best solution.
