That plug hole in the 8.75 housing is for filling it with gear oil. You want to be about .25" - .50" below that hole. I just stick my finger in it and bend the tip down. if I feel oil, it's good to go.
There should also be a tapped hole for a vent on top of the housing towards the driver's side. It's for a vent that keeps pressure from building and blowing your seals. And it holds your brake line distribution block.
