A Baffling Early A-833 Question...

The baffle is not in the 64 service manual but it’s in the 66 manual. I’m thinking it has something to do with the location of the vent. The vent on the 64 with (no baffle) is located at around the 10:30 location when looking from the rear of the tail shaft housing and on the 66 and up transmissions (with vent) the vent is in the 12:00 location
