I'm not sure what there is to Disagree with, I'm just stating the facts. I checked a dozen different factory service manuals, multiple 67s, not one had any indication of a second printing (doesn't mean they didn't). It didn't matter what year make or model they were all printed in August. So every year the were selling cars before the service manuals were printed.
Just because you think they could have or should have doesn't change the fact that they didn't, they saw no reason to. In fact it would have gone against what they had been doing, waiting till the cars were into production so they knew all the final changes.
There was already a system in place to issue Service Bulletins to cover issues with the Service Manual, this was no different.
I never saw this to be odd as much as I saw the late release of the car itself.
