I'm trying to spec carrier bearings to go with the true trac.the 3rd member company says use 3.063" w/the 31 spline set up.strangely enough they're the only ones that carry this exact size and @a premium.the rest of my 31 spline findings consist of 3.062" & 3.0625"i know this isn't a LARGE difference by any means and I'm not @the point where the carrier's out of the housing (that's a ways off) so i can't measure.I'm also not the one assembling this new assembly so I'm trying to get it the rite parts and not waste anyone's time.any thoughts on this small difference?
