I am getting conflicting information trying to decode this rear end. Many,many years ago (like 20) I had info that it was a '67 12 bolt Posi diff.
numbers are C00119 B . There is a stamped letter E underneath the stamping.
Model number is 8875745N.
Any help will be greatly appreciated. I intend to list it and would like to be as accurate as I can.
TIA

That casting number is actually 3875745N which is a 1966 Chevelle 12-bolt.
