Also, there is a long pc of metal that joins the motor to the steering cable ,it is completely rusted as are the bolts that secure it to the motor.what is involved in replacing this pc and are they bolts or studs that secure this pc to the motor . It attatches to the motor between the power head and motor leg . thanks for any info
