Just looking at the axles quickly they have a WMS-WMS of about 68in with a gear ratio of 7.5:1 with factory lockers. I can put my 15in wheels on over the stock drum brakes with a back spacing of about 3.5in. I got the tailshafts and the torque tubes with them so its easy to convert then to a normal flanged pinion setup. The only thing hard (not so much hard, more of a PITA) I got to do is cut the front axle housing and swap the axle tubes so I get the pumpkin on the RHS.
Damn sweet axles.
