Haha. You just /thread'ed your own thread.
Andrewtech runs 3 quarts of Lightweight Shockproof topped off with the Motul in their gearboxes, so I'd trust that. You can stick some Valvoline synthetic 75/90 in there instead of Motul if you can't find it, that's a fluid recommended by Dylan at DS1.
And yes, the rear diff will work great with a regular 75/90.
