I suggest you go here
https://shop.efv8.org. The book for the forty is not shown, I believe an update is being released. Try again in a couple of weeks. Try posting your question on the Early Ford V8 Club site,
https://www.earlyfordv8.org/forum/ Maybe someone with the current book can look up the information for you.
