That hasn't been the rule for a couple years. All automotive motors (that fall into the categories in the manual, seat, door, window, etc) are legal motors. So all the old window motors, or motors got through the old scrap yard donation form thing etc, are all legal if they were unmodified prior to this season. At least that is my interpretation of the rules.
