Replaced the gearset in the Deora replica, and need a current part number for the big gasket.
Anybody know what it is?

I use the Felpro Gasket , my catalog is packed though & Ultra Blck silicone , the gasket helps to fill the not quite perfectly flat surface

Both differentials in my 4X4 2005 Dodge Ram use red RTV on the differential covers with no gasket.  And absolutely no leaks.  RTV is one of the major reasons manufacturrers have been able to make cars that don't leak oil.  I just saw an episode of a car program on tv this weekend where they were installing a intake manifold on a SB chevy.  They threw away the end gaskets that came with the intake manifold gasket set and used red RTV.  It also completely seals valve covers.  All we had when I grew up was Permatex No 1,2, or 3.  Even with that messy stuff, the old valve cover gaskets always leaked oil.  The only RTV's that I am familiar with for car work are the blue and the red.  Red is the high temp variety and usually costs more.  Blue is what I usually use for oil pans, etc.  You do have to be careful to not squeeze the stuff completely out of the joint by initially tightening the nuts too tight.  I believe the correct procedure is to do an initial snug up and then let the RTV cure before the final tightening sequence.

I did use the blue RTV silicone under the front differential cover on my 1996 Ram 4x4 last summer with absolutely no leakage.
But to be honest, it's been about 20 years since I last changed out an 8.75 pumpkin, so I'm a bit rusty.
And I used to use the Permatex black glop back then.
