Recently bought this rear axle for installation in my '38 ton and a half whenever I get around to picking up that project.
Width across the axle flanges is 66.5". Weight rating is 11,000 lbs. Gear ratio is 4.63. Wheel bolt circle is 10 on 7.25", wheel hub pilot is 5.25" in diameter.
It is a Dana 80 from a '99 1/2 GM truck according to the assembly numbers on it. The Dana websight has Parts Lists and Service Manuals on line for it. This rear end appears to be popular with the 4 wheeling crowd so there are lots of parts/tools available for it.
