Do a search for some of my posts. The Eaton rear end was used from 1946-1970. The dropout carrier until 1972. I updated mine with Bendix brakes. I did all the hard work/research. Now all you need to do is copy me.
Mine has 13" brakes on the back. ALL parts are 100% NEW, not rebuilt. I got a 4:11 carrier out of a 68 Chev 4x4. It bolted straight in.
Keep the Eaton rear axle. It is full floating and a real monster. Very tough.
I will help you in anyway I can answering questions. Please ask.
