Truck axles have thicker tubes and are a lot easier to find, since your cutting it anyways it doesent matter what brand it comes out of. The side gears in the carrier are the only major factor. A friend of mine picked one up outta a ferd truck newer model, 4.10 ratio trac lock for 30 bucks.... Only snag he's hit is the side gear splines, strange wouldn't spline him a custom length axle.. But moser would, or the other way around. I think he's got 31 spline??? Watch out because a d 70 looks like a 60, there is a cast in 60 on the housing if it's a 60 and a 70 if it's a 70.
