91 300e passenger side euro headlight LENS

I have a '91 300E with Euro headlights ..... a rock hit the passenger side lens and the lens is broken.

Does anybody know where I can buy just the passenger side Euro headlight LENS ...... OR ...... do I have to buy the entire headlight assembly .......

I called importvision and they have the Euro headlight assembly (pair) for $200.....

any help would be greatly appreciated.

thanks again
