Looks like the differential cover was on wrong. There are grind marks on two sides of the inside of the cover - must be from the ring gear?

How does the cover go? I presume the two bulges in the cover are supposed to line up with the ring gear? Does the filler plug end up higher or lower than the center of the cover?
