Check the RPO Code, this is not an Eaton. I have seen this myself. It is a 72 with a Dana Rear End. I got all giddy when a buddy of mine called me about a 1972 big block automatic coil spring 3/4 ton he had found, he bought it for the big block and turbo 400. I knew it was gonna have a Detroit Locker and an Eaton 3.90 in it. It sadly has a Dana rear end. He grabbed the drivetrain and the rest is still in his yard.
Longbox55, if this an Eaton, please post the RPO code.
