There were two seals in the era that I'm most familiar with. The 8A-4676 is likely the one you need but the confusion always comes in with the 8M-4676-A seal. The 8A-4676 is has a 3-inch OD with a 1 39/64" ID. The 8M-4647-A seal has a 3 11/64" OD and a 1 9/16" ID and they look different too. Crossing the seal over to another part number always gets messed up by the aftermarket seal manufacturers.

The 1949/59 Ford parts CD I have lists something else for Sedan Delivery and Wagon in the 1949 to 56. It has part number B6A-4676-A which is 3 5/32" OD X 1 9/16" ID. All of this stuff makes it very confusing.

The other thing that confuses the matter is the possibility that the car doesn't have the original axle assembly. Anything is possible after all these years.

A Dana 44 has a "44" raised casting number under the right side rear housing bulls eye where the transition to the axle tube starts. It also has a removable cover on the back. The Ford units all have a removable 3rd member whether its the early type or the later 9-inch and they remove from the front with no removable cover on the back.
