Mike: Something new every day! They do appear to be aftermarket, all of the Ford cases ( I have seen ) have the part number indented into the casting at the rear of the case just under the two holes. Do either of these cases have a vehicle serial number stamped above the inspection hole?
I have two NOS transmission cases, Part Number 78-7006.. I'm not sure if they are FORD made, but they did come from a FORD dealership, years ago.
I have been using them to hold up shelves made from 6 foot long Model "A" Express truck running boards (The Waltons).
