He rebuilt the 8 inch third member that I'm using to replace the 4.10 Dana 44 in my '54 Ranch Wagon. He is an old time rear end and trans shop. He came highly recommended to me by numerous knowledgeable people. He will respond to emails but it may take a couple of days. If you call, will talk for a while but he may just have a solution for you.
