'65 Barracuda Wipers

I tried switching the wires but then the wipers wouldn't work. My car has a variable motor and switch. The Valiant series AV-2 differs from the Dart, where the wiper motor is under the hood. Barracuda's wiper motor is under the dash and not the same motor as the Dart. It is very similar to the AMC wiper motors. Timing the park is done inside the motor. I called Dave Bass for more info on this procedure. He told me to remove the motor, remove the switching plate on the back side of the motor, and move the arm 180. I tried that with no success so I called him again, and he told me to pull the switching plate again and turn the thin metal plate, inside the gear assembly, and turn it 180. Wallah! It worked! Interestingly the plate appears to be symmetrical and didn't look like turning it 180 would do anything but it did. Now we know.
