Power steering sector casting number chart?

I have several power steering sectors and am looking for a decoding chart that has the casting numbers and years used. Nothing listed in the white books, and a Google search doesn't come up with anything usable, any suggestions?

No list anywhere? I have a couple different part numbers, but have one from an A-Body and one from either a B or E-Body with the same numbers. Is is just the pitman arm that is different?

The B and E bodies have larger sector shafts. That may have changed in the mid 70's though.
