If you don't care about originality, the Audi A4 wind deflector works in the E36. I have one that I used for years until I got an insane deal on a hardtop and wind deflector from an old lady that had them sitting in her garage.
The pros about the A4 deflector is that it folds in 4 and can easily fit in the trunk. The con is that it does not lock in like the E36 one under the cover and of course does not give you the "factory look"
I still have my old one, it managed to get a couple holes in the horizontal section while in the basement.
$50 if you want it.
