I was a Fords Parts Manager in the mid-70's for a couple of years. Ford has the best parts numbering system of any car manufacturer hands down. It was Henry's design.
It is simple and when you know the sequence and the 'why' of how it is set up with Basic Part Numbers according to group, and the prefix and suffix attached, you can decipher with pretty good accuracy, about any part number and know exactly what models and years of car or truck that part fits w/o having to look it up.
Now there's GM and Mopar's numbering system
