I think you've hit on a key aspect of the gross weight change.  I
remember hearing discussion relative to this point.

The CAA did add a few not too terribly expensive things to do to upgrade
the fleet of C models to the D to get the benefit of the added gross
weight and, as you say, the D model is under the Normal category. The
limitations of the D model's up elevator travel were related to the in
flight testing, Fred Weick told me.
