Went to replace the gear on my passenger seat today and noticed the connector tube between the motor and the gear is missing. Two questions. First, any idea what part number that tube is? All the diagrams I'm seeing online just have the gear housing and motor listed, but not that part in between. Second, from the motor pics I can find, there appears to be a threaded plastic piece pressed on the end of the motor housing that the tube screws onto. That is missing as well. Does this mean I'd have to order a whole new motor to get that part? Appreciate your thoughts.
