Given that we have no way to scrutineer "hardness" - and no engineering drawings nor any current NOS examples against which to compare it - in theory you're correct, but in reality your standard is not practical.

In correct. See 9.1.3.C above.

If I were trying to keep IT cars in the class, I would allow any drive system parts to be updated with bigger heavier parts. Diffs, axles/drive shafts etc.
We've argued that point in the past, and it's always come down to "warts and all".
