I don't think the Dana 60 was even in production in 1952. If the center housing can be unbolted and dropped out of the front of the unit, it's definitely not a Dana axle. I believe the Chevy rear end was an Eaton unit in the early 50's, and a 3.73 ratio was not available. The highest gear was a 4.56:1 that year, IMHO. Later model 3/4 tons with automatic transmissions went to a 4.11:1, but they're very scarce.
