thought I'd share (4/2021) my OEM (2013 GL450) rear wiper blade bit the dust ... bought this from amazon and removed the blade and installed it on the OEM arm (b/c the arm is fine and has the Benz emblem ... LOL) but in theory, this bosch arm should fit as well) ... so far so good

You can get the wiper inserts themselves. It's a 12" narrow.

Less expensive option.
