Rear end not centered

My Cuda is off 5/8" and I carefully measured things to figure out why and the problem is not with the leaf springs or how much the drivetrain is offset, it's the design of the axle. With stock tapered roller bearings the right side has an adjuster that forces the right axle towards the left. The only easy way I see to perfectly center the axles is to replace the tapered roller bearings with non adjustable "green" bearings that eliminates the adjustment. Or cut the spring perches off and re-weld them on the axle housing "off center" enough to center it. Hope that makes sense, LOL
