The proper windshield wipers for W126's. Please read.

Ok I am guilty of this also, after reading many of the posts here I have seen that many of use W126 owners don't have the right wiper cages on their cars.
These are them, from Fastlane:
P7032-19643 Wiper Blade Set Bosch IN STOCK $74.96 $57.69

The ones you get from Autozone are not the right ones, I just went through this I didn't want to spend the money. But the cheap ones do not work right and will cause problems. This is just part of owning a W126 you need to buy the right wipers.

Just for the new guys most W126 owners seem to have the same problems.
