As far as I know the only things available for the 14 bolt 10.5" Full-floater are: Open-diff, GM Gov-loc, mechanical locker, Eaton Positraction, Lock-Right, ARB Air-locker.
Am I missing anything? I really wish Eaton made an E-locker like they do for the D60 on the front of my V3500 and the D44 on the front of my K20.
