Dana 60 rear axle specs of a 79 j20 with Quadra-trac

[j20owner]

I was wondering if anyone knew what spline counts and axle shaft length are on the pass. side offset Dana 60 rears on these trucks. I'm thinking of putting either an Ox locker in or a Electrac electric locker in. Any help would be appreciated.

TIA
