Filler plug, Drain Plug? 1995 240SX

[weg240sx]

Ok so I just bought this 1995 240 SX for my daughter and went to change the drive axle oil. The only problem is that I seem to only find one of the plugs in the rear end. I can see a plug toward the bottom/back of the rear end, I believe that this is the drain plug. The thing is I don't see or feel the filler plug. I know that this is one of those questions where you are saying, you've got to be kidding, but I just would like to know where both plugs are for this rear end.

Lay under the car with a 1/2" socket wrench + extension

Find the drain plug

Move up from the drain plug towards the driver's side of the car

On the driver's side of the cover above that part of the subframe that the cover of the diff bolts to you will see the filler hole.
