FJ80 Axles aren't quite full width but they're about 7" wider than the standard solid mini axle. You can get longs for the front of it too, which are bigger and stronger than the mini's and they came standard with the high pinion 3rd. The rear 3rd is unique to the FJ80 but it is a fill floater from the factory. If you look hard enough you can find ones with factory diff locks.
