bignbad, I'm pretty sure the only difference in those two axles is the size of the brakes. At any rate, the bearing numbers are 99.9% stamped into the bearing, so if there is any question, just bring the bearing and whichever seal is least mangled to your Napa, and they can match them up for you. Bearing part numbers are common across lots of manufacturers, but a Napa can definitely cross them for you if you have an off brand. I've also found rockauto.com to be a great resource for looking up parts. They do specify which bearings are for the Dana 60 and which are for the HO52, and in many cases even give you sizes.
