Post by: frotosride on December 22, 2011, 09:59:45 pm

For fututr reference and all those who google...GUILTY..... the outer spline count (inside the hub/knuckle/spindle) that is on the '87 corporate 10 bolt 8.5" ring is 19 spline count....Im going to pop the cover on it to ck for wear and debrise plus synthetic gear oil upgrade... anyone out there have a good deal on  LOCKER for this Diff? I really need one. I want it for the rear diff. first because theres greater advantage there if i have to upgrade one at a time..and thanks to todays military pay (which I am greatful for) I have to wait.
