Hi All:
Look for a US-market FZJ80 at the wreckers. The rear axle will be the "9.5 inch" and may, or may not contain a factory e-locker.
The factory e-locker looks different than the stock open rearend in that it has an activator mechanism bolted on. Very obvious!
In my previous post I was a bit sparse on the details of the install. A buddy has done it in a couple of different rigs so I have gotten used to this retro-fit.
In addition to the long-spline inner axle shaft, one will need to cut-out the axle housing to allow fitment of the oddly-shaped e-locker third member. You will also need to figure out how to activate the e-locker; IIRC my friend rigged-up a simple electrical switch with relay.
Good luck!
Alan
