If anybody has an early E34, they probably know what I'm talking about. Instead of a downward hook to hold the wiper blade like any normal car, the arm is backwards, and the hook dips down and then hooks back up. It's weird, almost backwards, but mine is so old that it's begun to bend and the metal now scrapes my windshield after I replaced the blade.
Suggestions on whether it's possible to replace it with a late model wiper arm? Also, where can I get one? It's destroying my windshield!
