I treated my car to a new wiper unit after 25 years faithful service (and it was from a breakers when I got it!!!) And the new unit along with new gear boxes worked a dream, but as it was all less floppy that the old worn units I needed to tweak the sweep a little longer.. 120 degree wheel replaced with 130 degrees and all is well in the world.... Especially when I'm driving in the rain!!!
