I have in my garage at this moment a Dana 60-2 rear that is factory equipped with 5 lug axles with a 5 on 5.5" bolt circle. The axle tubes are 2.785" in diameter rather than the more common 3" or 3.125". This unit is equipped with a PowerLOck carrier and 4.10 gears. The OEM use was in the Jeep Gladiator pickups from the early 60's. This not a floating axle unit, it is just like a car but with 12" brake drums and requires 16" wheels. I had plans to use it in my Ramcharger build, but used a 3/4 ton truck housing. This needs to find its way back to a Jeep
