red58....looking at your wiper pics I'm guessing that one side of the gearbox is removed and it has 2 studs where the wiper transmission arms go (both on the same side)?? This unit is definately NOT what I have. I see the slider control and this is the same as the one I removed from the '59 as I dont need it with the motor I have. I have my wiper motor connected to a large toggle switch for now with the plan to use either a rotary or push/pull switch with an original chrome knob attached. Please post some pics of a complete unit if you can as I would like to compare 2 other motors I have.
59Patchy...my transmission arms also have a 90 degree bend/twist to them. Also the passenger side arm has a large offset to it compared to my other set of arms. I have a feeling the motor without the arms or visa-versa would give a man gray hair attempting to make things work. I am going to file these numbers you gave and if I ever have to remove mine again I will compare.
