Honestly, I do not know if you need to change the windshield for installation of the oscillating wiper.. but, the windshield was changed when the new wiper was introduced.

It has a large radius cut out of the bottom in the center to accommodate. Seems like a lot of extra trouble for MB to put a big cut on all their windows if it did not need it.... especially on their 'cheap' model.

I bet the updated type has less streaks, cuz even on my new window with a new blade it is hardly an acceptable view.
