Since yours has the threaded style shifter cap it is the later one. I'm not sure when they changed. I do know the shifter cap that is held in by the Pins is considered the early AA Trans. I believe they came out at the very end of 1929 and only in AA Trucks. They were a common Dealer retrofit into Model A's especially in the Pickups. They are the Beefier Truck Transmission, very Heavy Duty. They made them well into the 1950's the gears that is. The cases changed often.

I finally found the casting date, under a layer of grime! 2-12-31....the day before yours! But its on the shift tower and not on the case....and so far there isn't one on the case itself..different foundry?
Been mulling changing back to a 3-speed....were there different torque tube lengths? Measured a 1930 today and it was 49 3/16 from the back edge of the clam shell to the front of the flange at the differential.....mine measured 49/1/2"....does that sound right, or has the tube been altered?
