All the Durant & Star Transmissions from mid 20's to 1929 are the same. These are all the ones that have the trans mounted separately and connected with the Spicer u-joint with the rubber balls.
The service manuals have a diagram of the trans.
If you can't find a gear close by, I should have a used one. You may consider an entire trans also.

I just finished building two transmissions for our '27 Stars. I have many clean, very nice gears available if Frank doesn't have one.
Also, All Star second gears are the same. I'll need a pic of which gears you need just to avoid confusion over terminology.
