Post some pics of your diffs if you can LJ/RJ70 only please. Also if anyone has any spares I need some, it is for tech and will involve more cool goodies being available.
I have a buddy with a 1989 LJ73 who lives in the Seattle Metro area (Shoreline.) His rig have a factory LSD rear diff, and currently the front electric locker from a FZJ80. I'm assuming he still has the stock open front diff.
