Turning to things mechanical, this is the front diff, out and on the bench and split apart. That's about as far as we got with it. After measuring it from every angle, we determined that nothing could be done to enhance it with products currently available. An ARB Air Locker for the Toyota 8-inch diff will physically fit, as the diff is a regular Toyota 8-inch carrier. But the unit employs 52mm bearing caps, so ARB has nothing developed to get air into the Air Locker diff itself.
