Wiper Motor Transmission Arm for 1971-1973 Mustangs.
This is a quality reproduction replacement for your original stock wiper motor transmission arm. Also known as a wiper motor linkage arm.
Over time, a wiper motor transmission arm can become worn at the hinges, causing rough or bumpy movement. You should replace your transmission arm at the first sign of problems, because if left unfixed, this can cause your wiper motor to burn out.
