[Skyline2.0]

CirrusCR22, I'm hopefully getting around to the rear diff oil change in next week or two. I was under the car just now and saw what I believe is the fill plug. Is the fill plug on the right side of the differential, in front of the right rear drive axle and next to a black box? I'm wondering if I can avoid taking off the black metal skid plate and just undo the plug to extract and refill. See attached photo.

Thanks again for your help.
