Default Clutch shaft AA and A the same?

I believe the clutch shaft pin broke or sheared inside the bell housing on my 1928 AA 4 speed transmission. Is the shaft the same as the model A 3 speed shaft? Are the bushings the same?
I would like to order the parts before I tear it all apart.

The bushings are the same the shafts are different.

See page 509 of the Service Bulletins.


First picture is of an AA shaft, second is an A shaft...you can see the offset....

The 4-speed shaft has a AA number but the bushings appear to be the same as the A.

Order three bushings. On the operating side there should be a longer bushing I put two and trimmed one.
