That is the link part casting number only. 555 & 556 are the entire assemblies and are all correct. You never have the assembly number cast on a part. If you find a 9N, 2N, or 8N prefix, it is only the part casting number. FORD nomenclature defines the part prefix as which module the part was fist used on. Examples: 9N-555 and 9N-556. If a an alternate supplier was used, or a minor change made, a part suffix would indicate by letter, i.e., A, B, C. If a major change was made to the part, for example from the 2N-10000 generator to the 8N-10000 generator, then a new prefix code was released with it for the new part. Basic part groups were all standardized. 10000 block was generators, 17000 block was tools -follow? Yes, if part is cast with original number, it is the real McCoy and not a repoop.
