I'm having a heck of a time finding a driver's side headlight wiper arm and blade. I've found ones for the passenger side, but with my luck that's not the one that's missing. If anyone has an extra one they'd like to sell, let me know!

 

Try Ebay.. LOL

I know its been a great place for me regarding auto parts..

 

There are a couple 850's being parted out on volvospeed.com. Maybe find one there. Or just take them both off. I hate those headlight wipers to be honest. I think they look goofy, and people are always making comments about them and the only time they do anything is in a snowstorm and I rarely drive in snow.
