I found a 1 Ton Dually Axle in a local junkyard, I intended to swap with my '71 GMC C-20 (Dana 60). Due to the Right hub bearing siezing to the adjuster AND lock-nut, Stripping the threads on the axle-tube in the process. It was under a '67 or '68 Chassis/Cab with a dump bed. After making a deal and upon delivery I noticed that It Was NOT a Dana 60, (Or any other series Dana that I've seen). I've talked to everyone I know and all I have got was a possible ID of an Eaton Unit. If any one Can Help I would really appreciate it.
