Can understand the need for more rigid mounting on the nose of diff but the overall cage / rear frame design and support of the diff wing has nothing to do with this failure. The tortional forces on the wing bushes are nothing compared to those on the nose mounts. Use the correct bush caps, mount the nose properly and diff won't dismember itself.

A more contructive input would be telling everybody where you think this additional triangulation needs to go (?)

The diff was able to move so it broke that is simple to understand. The diff needs to fixed so it can't move or at best severely restrict how much it can by using the correct rubber mountings. My choice would be solid mount the diff and triangulate the chassis.
It's obvious where the rear cradle is weak as it is open rectangles with no triangulation and the diff is fixed to this........less is more usually and take a good look at how Marc Norden has done the MNR, simple yet very effective.
