Well guys the casting number is visible , it is N 3969277, definitely a 1972 model, 10 bolt open.
From the pictures I browsed, it looks like an 8.5.
Any way, I have no use for it, It would be sad to see it go for scrap / salvage

I like to learn something every day and I just learned that 1972 Chevelles could have an 8.5" diff.
This would be a very desirable unit so hopefully someone will take DEJ up on his generous offer.
Spread the word.
Hey there,
Well the differential is gone to a good home, it will be installed in a 1969 Chevelle.
I am glad it is not going to a salvage yard.
Have a good ( safe) summer on the highways everyone.
