I don't know if someone filled in the original holes and cut new holes in the 1953 cab, as I no longer have that cab, and modified the arm length (they do look like they have been cut and welded back together) but they definitely aren't long enough to go from one side to the motor and to the other side. Doesn't make any sense that they would do this as it would be a lot of work for basically nothing! I guess I could cut the arms and add a length to each side so that they reach the motor. I would think that if I made sure both wipers were in the "parked" position when I did this it would all work out fine. Thoughts? The other option would be to look for some stock arms that are the right length.
