Thanks to all for replys. That's what I needed to know. As to why, I was trying to see if I could find a ready to go centered rear axle to put in a landcruiser frame. Stock width is 55.1". This weekend I was able to find the minitruck axles I needed for the conversion of the stock LC axle. I'm working up the nerve to actually cut the housings on my mitre chop saw and bash the two. That is the preferred option as the LC has a 9.5" ring gear and 30 spline axles.
