My September 30, 1969 NJ built 70 Mach has the seperate letters (from day one, 59K mile car) , The seperate letter mouldings had a problem with the letters that covered the screws falling off, The later moulded letter mouldings fixed the problem. I bought 4 of the large fender mouldings NOS from an ex parts manager friend of mine that took them home after they used the removable letters off them for warranty claims in 1970. Appairently you couldn't get just the letters, you had to order the whole moulding from ford...... Hope this helps, John (BTW, I'm guessing your car doesn't have the engine size callout in the hood stripe either.....)
