That’s a good article. But the key here is that the number on the part is not the part number. Yes, with Ford’s infinite wisdom they put the engineering or ID # on the part to stay with it forever, but put the part number on the box - to be thrown away. And then the Master Parts Catalog has you look things up by the part number.
I have cross references, so can look some things up by one # and find the other. But they work in fairly limited date ranges, like 1980 - 86, so can’t always determine what the part is by the number. Glad you guys got that one figured out.
