I agree that it would be nice if they had stated such. Caveat Emptor
Sadly my post is too late to help but we could have helped you out on this had we been asked the question. That's the way the 4-5-6 manuals were published. The '63 manual has all the data, the supplement manual has whatever changed for the specific "later model" years.
I purchased a '63 and a '65 supplement as hardcopies at a swap meet. Sometimes the old school method of seeing what you get before you buy is the best method.
