I was looking at the wrong input gear. It's 29/15 for the set I was thinking about. They have the odd 022A prefix part numbers. Some of the Mercury transmission stuff was made specifically for the Mercury line in 1939. They even had their own case part number. They eventually changed for interchangability. They were also used on the V8 60 applications but they had a stump puller rear axle ratio.
