I got a pair of new wiper arms from a surplus dealer and they do not fit my wiper motor shafts. I compared them to the old ones and it looks like the bushing is different on the new ones. It is not recessed in the back like the old wiper arm bushing is, and there is not enough exposed threaded shaft to allow the acorn nut to be crewed on.
I was not aware that there were different styles of air motor shafts and different wiper arms. The only thing I really needed was the end wiper arm bracket which holds the wiper blade, and which is replaceable on my old wiper arms. The new arms have that end bracket riveted on, instead of screwed on.
The question I have is: Are the old style arms with recessed bushings still available, and if not can I simply press out the old bushings from my old arms and press them into new arms? They seem to be metal bushings, so I believe that it should be possible.
Also, are these end brackets that hold the wiper blades available somewhere? They seem to be the weak part of the arm - they rust through on the end, and will no longer hold the blade in place.
