The S 976 B is a "stamping" number. If you need parts for the diff that's the number to give your dealer.
It's an 8.8 with 3.55s like you assumed.
The 7J10 is a build date code.

Thanks for confirming that Racreguy !
Lost the driver's side output bearing , looking for a used or rebuilt replacement.
Weird that this bearing went out - hardly ever used 4WD.
