I went to look at a dana 60 rear end yesterday and took my list of BOM numbers from two websites. They listed the rear end as a 70-72 B body. Of course we all know that a 71-72 b body is a different cat than a 70. Of coarse they listed a 69 e body as well. The numbers are 603222-2 with a date code of 5-13-2. Looks like a rare piece to me. My question is what website has the correct info? The ones I have found do not even list a 71-72 b body housing.
