Model T Doors

I have some doors for a 28/29 Model a Truck, and I know that they also fit some Model T bodies. I would like to know specifically what Model T bodies they are interchangeable with.
 
The 1926-27 Model T Tudor, 1926-27 Model T Coupe, and 1928-1929 Model A Ford Closed Cab Pickup doors will all interchange. The Ford AA truck doors do not.
 
How are the 28/29 AA truck doors different? I always thought the truck cab was the same as the pickup cab.
