An adjustable, Set 7 bearing is a needlessly complicated design that weakens the differential, limits side gear spline engagement, and is prone to leakage and dirt/water contamination in many applications. In addition, axle flange stand-out is not held constant unless you blueprint the axle lengths.

Although most people won't have problems with the snap-ring style Green bearing (not the crimped on flange, RP-400 design still sold by Mopar Performance), the non-adjustable, 3.15" bore Timken set 20 tapered bearing is the strongest, commonly available wheel bearing. Unfortunatley, special housing ends are required to run this bearing on a Mopar application.
