Hey, I have a quick question about changing wipers blades on the X. Do I need to change the complete assembly? or just the rubber blade? reason I am asking is that i bought a set of the Bosch Micro Edge and i was about to change them... ( unhooked the old ones from the arm ) and I noticed that I would not be able to retain that broad piece of plastic that is attached to the driver side arm.

Sooo. I stopped.. and rethink the situation.. and decided not to change anything yet.

Any input?
