Does anyone know if the 60'-72' 3/4 ton 2wd coil spring trucks came with a Dana 60 rear end? I ask because I'm interested in replacing the 12 bolt in my '66 1/2 ton 2wd with a Dana and I'd like to be able to find a donor truck in the salvage yards with a Dana in it. I realize that the housing ends would be different. I mainly want to find a Dana housing that would bolt in on my trailing arms. Thanks in advance, Chris
