Nothing was set in stone.
Feets, I don't know how to respond to ya. I'm not arguing with what you said. I simply stated what was told to me buy the new car salesman, when I went into my friendly neighborhood Dodge dealer in the fall of 1970 (approx, 3 months before you were born) to spec. out a new 1970 Challenger RT 440 automatic.
I was told that If I wanted any gear ratio higher than a 3:55, then I would need to order the Dana. I asked him specifically, did that go for the Hemi too? He said yes. That being said, I would assume that meant the 8 3/4" was the standard rear end that came with the Hemi, (which I thought you were saying also).
My 1969 Hemi Super Bee, had the Dana, it also had 3:91 gears.
That's all I was saying.
