I could do with a new pair of wiper arms. I have found some but there are two types.... Where the arm bends at the wiper end some have a 10degree bend others 20degree. This can be compensated by moving a notch or two on the wiper motor spline but the wipers will sit 2" higher up the screen with the 20degree one (when at park) which is very noticeable. Does anyone know where i can get arms with the smaller 10degree bend?
Have you considered wiper arms from a Yugo? I have some I've been meaning to use on my 131. The angles are correct but the arms are about an inch longer (I guess because the Yugo's windshield is larger). This might require a smaller wiper blade on the passenger side, otherwise it would overlap the edge of the windshield.
Mine are badly pitted and several coats of Rustoleum didn't fill in the pits.
Trouble is some Yugo arms are bolt on. My 87 does not have bolt on wiper arms but an 88 parts car does.
