I just re did mine a week ago on a 73 Dart Swinger. Be sure the bushings are pressed in the arm all the way. On motor side the bushing must be pressed on the tit on the wiper motor arm. Not easy or fun. I had to pull glove box, cluster, and motor from engine bay. Wound up using a very long flat tip screwdriver to push on the arm with the new bushing on the wiper motor through the glove box.
