You didn't read my post - at least the part related to Change Product Rule.
CPR basically says unchanged aspects can retain their original cert basis, while new or changed aspects need to step up to the latest regulations (and amendment levels).
I suspect, aside from some structural stuff, precious little of the MAX is still certified to the 1967 rules.
