Just got myself a nice old Oshkosh heavy haul tractor. It's not as bad as it looks- the guys who owned it started restoring it, did most of the hard stuff, and just never bolted it back together. All the pieces are there, including a monster Tulsa hydraulic winch. It's got a good running 335 Cummins , 5 speed Allison with retarder, and a 2 speed box behind the Allison. Anyone know how to ID old Rockwell rears? The tag on the top reads 175 604 6.58, the lower tag says 04640 HAPX 6.58 6-77065, with 4-67 stamped down in the corner.
