You have a couple of options. One is to buy an entire "generic" assembly which will probably not be an exact match but have the same features. The other is to simply make a new one using the current panel as a pattern. You can buy plastic sheets at Lowes/Home Depot etc.
I believe this one has the same features as yours and even looks like a direct fit.
