Packard built their own differentials up to 1955 and only changed to Dana in 1956. Dana 44 for Clippers and Dana 53 for Packard models.
Not sure about availability of new which would have to be NOS, but any 3.54 ring & pinion set from 1954 or 1955 would work for your car and this was commonly used for the Senior models.
