That'll work, however some arms are notched and that cannot be done. Is this just a problem with the park position? There is a metal rod [about the size that of a coat hanger] that parks the wipers and tells the motor when it has reached that position or something. Occaisionally this becomes bent, and the wipers do not park properly. A quick way to test this, is turn the wipers on, and then off [so they park normally, on their own]. If they don't park all the way down under the cowl, push them in by hand. Do they go under the cowl? If so, that rod is probably bent. Somewhere around here is the thread with the instructions.
