Correct 3 spd wiper motor part number for 8/23/68 built 69 Dart GT

I am aware of the date code on the above motor and realize it is not correct for an early 69. I posted this photo for reference of the later motor. I am working with Kim at Passion4Mopars on this issue. She believes the correct motor would be the 2983033 motor but is not 100% sure. I am hoping that someone can provide photos or other information on an early build A body with the original motor to confirm this. The parts book lists the #116 motor only for A body. However, Kim does not think they were being used yet at the time this car was built. Hopefully someone will come thru with some evidence. Thanks!!!
