Passenger side Euro light lense...

[spaeth at gorge.net]

I have been a lurker here for many years. And we daily drive a 91 200 Turbo Quattro Avant. I have Euro lenses and the passenger side is cracked. It is 
causing moisture to get in and the light is barely working now. This is our main winter ride. I have checked quite a few places and even tried on German 
e-bay. Does anyone have a lead on this lense or even a set of lights? Any tips on how to more accurately search German ebay?

thanks
