I have a nos 3 speed wiper motor from a 74 Polara/Monaco and would like to use it on a 74 Charger. I know I have to swap the harness connector that goes to the bulkhead but I also noticed the park switch plate is rotated 180 degrees on the c-body motor from what the b-body one is. Any input? Can't find much out there on disassembling-assembling these units. Thanks!!
