Richard , you are correct in the part #. I also finally found it in my '70 Ford parts book and this # is listed for all engines and all models from 1965 thru 1970. They are dated 3EBC, 8CBB and 8BDB.
Not sure what I'll do with them. I had to buy a pile of NOS boxes of BRF 42 and AGRF 52 spark plugs to get the coils. Those I'm definitely going to sell cheap.
