Been awhile since I replaced the bushings on my Dart, but is there an issue when installing the linkage and clocking it correctly? Replaced the wiper motor on my father's minivan last fall, and just connected the linkage (he disassembled it, which included removing the arms themselves.). When I ran the wipers, it over extended the travel downward, and stripped the bracket into the splined shaft on the motor. Turns out I needed to clock the pivots, then the bracket to the motor, finally the wiper arms.
