i'll have to look again, but i'm pretty sure the i removed
everything except for the metal wiper arm itself when
replacing the front 2 blades. for the rear (non-bosch),
i re-used the "U" shape piece though.:dunno:i can't
remember.

hold on, do u mean the part near the end
of the wiper arm (closest to the middle of
the windshield)?

problem solved. i found the clip that u all
were talking about.
