Here's some more info from e-bay. A dealer accessory sheet.

I saw this at a swap meet Sunday. Ford accessory rear wiper kit #8A-18387-A. Never heard of this, but I'm not a shoebox guy. Anyone ever seen or have one of these?

The pin & bushing (or sleeve) needs to be a press fit into your repaired hole in the perch pin. Then like Mart says the pin will turn with resistance. The swivel must need some movement as the suspension moves. Here's some pics of mine.
Not sure about the "Green Bible" using those Model Symbol Codes, my Nov. '50 edition doesn't. I know these were used in the 1948 to 1956 Ford Truck Parts book.
