NOTES:

               *             Non standard performance upgrade.

               **           Axle spline must be determined for correct model selection prior to ordering.

               ***         Newer OEM Dana 30, Dana 35, and Dana 44 ring gears may have 7/16 bolts.  The OX locker flange holes must be

                               reamed larger to suit if necessary.  The carrier flange is case hardened and can not be "hand drilled".  Precision

                               reaming using a machining mill must be accomplished.

               ****       In many applications several differentials and axle shaft variants were used.  Verify differential and spline count

                               prior to ordering.
