Does anyone have info on the Trico vacuum wiper motor? I have 2 questions. How do I connect the arms to the motor? There are 2 nuts on the motor arm but they are odd in that they do not come off. It is clear to me that they need to connect there somehow. The other question is where do I hook the vacuum line from the wiper motor to? The carb or the fuel pump? Bonus question...are parts available for these? There must be a special tool needed as the heads of the screws are an oval shape. As always...thanks for the help! Bob
