This may be a crazy question but hey, this IS Car Talk!
I have a 2006 Scion xB. The rear wiper takes a proprietary wiper blade that needs to be purchased at and replaced by the dealer. I would really like to replace the rear wiper arm with one from another vehicle (I’m thinking of something like a Honda Fit, Mitsubishi Outlander or other J shaped wiper arms. Does anyone know if this can be done? Other than making sure that the size is appropriate and that the bolt stud is the correct size, is there anything else I need to be concerned about?
