two thoughts.......
one, I'd just look in junkyards...........and grab a more or less generic
one of a mini-van or whatever.
they are probably sold in the aftermarket as add-ons, for exactly your
purpose. ........JC Whitney comes to mind....

two, in the short term, put Rain-X on your rear window. ..........it works
just  great.
