Where did you get this number from? I read it as a 1978 (D8) Fairlane/Torino? (D, the 75 ed does not list a "D") Service (Z) number.

NPD also lists it as a part number on their wheel bearings...

According to the Ford OSI catalog, 1979 version, here is the lineage of part numbers:
1. B7AZ-1225-A (original) Note that this is the part number found in the 1968 version of the 1960-1968 MPC
2. D0AZ-1225-A (mix with) Note that this is the part number found in the 1975 version of the 1965-1972 MPC
3. D3AZ-1225-A (replaced by)
4. D5DZ-1225-A (replaced by)
5. D8DZ-1225-B (replaced by)

Note that the third character "D" represents the Granada for the 1978 (D8) model year.  That means that the D8DZ-1225-B engineering design was, for accounting purposes, charged to the Granada money stream.  It does not mean that the part is exclusively used for the Granada.

As a side note - I found it interesting that the Canadian Mustangs used a different bearing for this application according to the 1965-72 MPC

The Ford Motor Company documentation system was based on "simplicity". Most companies today have a "engineering drawing" (or a "specification document"), one that details the requirements (dimensions, materials, finish) for a supplied part and a second document that provided "approved" sources, maintained in the purchasing department. Ford had combined the two documents, the "measurement" and "source", into one from it's first days of production. It was one less piece of paper. Note: Ford was source - singular; the two document system was sources - more than one source. As a result, for any new source for that "identical" part, Ford had to create a new document, and a new part number. This is probably what you are seeing here with the multiple Ford service stock numbers, which were derived from the original engineering numbers. It's the 'Ford system".

Thanks for the interesting breakdown. Very informative.
