i just put a 12 volt windshield wiper motor on my 1948 plymouth special deluxe coupe. i bought it from speedway motors for a 46 to 48 ford passenger car. part # 913-56046 wiper kit for $124.99. all i had to do to fit was oblong the two mounting holes on the motor bracket. face the motor on the bracket to the drivers side and it has an adjustable swivel arm so that was easy to line up with my arms. my arms fit perfect on the swivel part. it comes with a switch so just needed a power line to hook
