Need to ID my 10 Bolt rear end

I am trying to ID my 10 Bolt in my 72 Lemans. The gear tag is missing and I don't know if it is the original rear. By jacking up the car and rotating the drive shaft, I know that it is an open diff and somewhere around 2.73 gears.

Is there any way to tell what kind of 10 bolt I have from looking at the housing? ( 8.2, 8.5, 7.5 ) I want to order a Powertrax Lock-Right and need to know which to order. Thanks.
