Ford's part numbering is quite good if you understand it. I found when working at a Dodge, Mercedes-Benz, Jaguar and small imports dealership that the concept Ford used and M-B used are similar.
Ford's middle section identifies the type of part, block, head, crank, manifold, gasket etc. First portion, the decade (C = 60s, D = 70s, E = 80s, F = 90s) then the actual year in the decade from 1 - 9, then the vehicle family it originated on
The last part is revisions, and can get long, initial is A and it goes up from there, sometimes with numbers.
MB, PNs are xxx xxx xxx xx
First group is chassis or engine 110 can be an M110 engine part or a body/chassis part for an old 4 cyl car
Second group is a class identifier, transmissions are 260
Third is specific part, like a countershaft
Last is updates 01-99
Again, once you have the code, you can look at a part number and know what it is.
