Hey guys, I'm finally doing a superduty swap into my jk. My new axles are from different year trucks 2013 front and the rear is supposed to be from a 2007, they delivered and the front measures out to a hair over 72". However the rear measures ~70 1/8". Is that normal for the these sterling axles? I have been searching everywhere online and cant find any info on the rear measurements. I figured a few folks on here have done the swap or might have some axles laying around. Thanks
