I like Bosch stuff. And their wiper blades are pretty good too. Here I am fitting an SP22 500mm blade with a 'hook' (sometimes called a 'J') fixture, which I picked up for a pretty good price here: amzn.to/45IMWFP
The actual length of the blade (500mm) doesn't matter a jot. If it has a 'hook' fixture, the method of fitment is the same across all vehicles, and it is dead easy, so don't go paying people to do it for you (buy me a drink with the money you've saved!).
Getting the spoiler onto the arm facing the right way round can be a bit mind-bending, hence this video.
Interesting Mousette fact: Bosch wipers have a spoiler on the driver's side wiper blade. This spoiler acts in a similar way to F1 cars in that in creates a downforce. This downforce pushes the blade closer to the windscreen at higher speeds and clears rain more effectively, thus giving you better vision. You're welcome.
