Fat Man Fabrications, that are well known for putting a M II under very many different cars, says exactly the same, so they offer some kind of updated strut rod stuff for the classic Mustangs instead.
And one more thing: The 69-70 Mustang are well known as rather nose heavy car, isn't they?
Not what the usual after marked M II kits are made for, I guess...
