That's the normal 1/2 ton rear used 55-62. Some people call it an Eaton, but it was actually made by GM. I believe the GM designation is either H033 or H035.

My 60 C-10 has basically the same rear, except with brackets for the trailing arm supension. The most common ratio is 3.90, but they were also made with 4.11 and 3.38, the last being quite scarce.
