If you are looking for a Dana 60 you might look under the Dodge trucks. My GMC 2500 came with the 292 six and a Dana 60 with 4.56 gears. I ran across a Dodge D200 with 3.54 gears and a posi carrier in a wrecking yard for $50. The Dodge Dana is the same except for different yoke splines and they use the smaller "U" joints. A 4 wheel shop had a yoke with dodge splines, but for the larger "U" joint.

3.54 gears, even with a six, made a bigger, single difference than most everything else I have done to the truck, except maybe the AC.
