While searching some of the local hole-in-the-wall junkyards, I stumbled across what was left of a mid-70's GM truck. From a distance I noticed it had some large diameter locking hubs so I thought maybe it was a 60 and took a closer look, though the weather was pretty crappy that day and I didn't feel like crawling through all the weeds, so I didn't get a real good look. The truck had no markings to tell if it was a K30 and the glove box tag wasn't readable, thought the guy said that it had an utility body and PTO winch, and was single rear wheel. Well anyway, the question is this axle had the large diameter (as compared to the typically Dana 44's and 10-bolts) locking hub, but the 6 bolts around perimeter of the hub looked to be a larger hex head bolt (instead of the smaller allen head bolts that typically hold the hub cover/dial on). Could this possibly be one of the old Dana 44's with the weaker external locking hubs, and therefore also have the smaller 260-x u-joints....I have never actually seen one of these. Or could this be a Dana 60?
