Larry, I just went through this with my 1962 300-H. I had a lot of good information from this forum. In the end, I contatcted the dealership and purchased the Mopar recommended 431 8058 oil and 0413 1806OAB additive. Drained and added the required amount, then drove a lot of figure 8's until the rear end quieted down.
