OK, my understanding is that locking diffs was a option only on FZJ80s. I was just reading on off-road.com and they said this...
"Locking Differentials
Locking differentials were available as options in all 80 series. From 94 on, they were standard in North America. The operation of the lockers is very elegant. When the differential lock dial is turned to the "Locked" position, it switches on a small electrical servo. The servo pushes on a dog clutch which is meshed with the splines on the axle shaft. The dog clutch slides along the axle shaft and engages on the side of the differential carrier. The axle is then completely locked. They were offered from the procuction date 8/92 onwards."
Ummm...did they say standard from 94 on in North America? Is that a joke/typo or what??
