I don't believe the interchange will work well between the 2 different shafts and gears. The 81A gear has an oil slot on it that will tend to bind with the helical spline on the 51A shaft because there isn't a thrust washer used. The 51A gear could be used with the 81A shaft if an oil slot is cut into the gear, not the best though would most likely work.
All in all I think a person would be wise to keep the 2 series of parts together and not mix them.
