72 280SE 4.5 REAR AXLE

[hk280sl71]

I have located a 72 280SE 4.5 rear axle of a parted out car that should be a 3.27 ratio. The seller is not that familiar with the item. Can someone convey where to find the stamping on the differential to verify this.
Pictures would be helpful. The seller is willing to look if he knew where.

Thank you

Even when you know where to look, it can still be hard to see. There is a slightly raised plate along the lowermost "rib" on the fixed axle side of the diff, towards the front. You may need some emory cloth or steel wool to see it. There are other numbers on the plate, but the ratio is the last of the numbers, and is kind of scribbled like this: "3,27"
