Picked up a taco e-locker rear axle yesterday. For a pretty good deal. Now I've got to decide what other mods I'd like to complete while the rear axle is out for the retrofit. Right now I'm thinking about making new upper and lower control arms, relocating the diff drain, raising the shock mounts, possibly raising lower control arm mounts as well and adding some more protection.
I don't plan on doing the retrofit right away. Most likely early spring when temps become more manageable in an unheated garage.
