Didn't you already post about this rig? The rusted-through part is terrifying, and if I understand the picture correctly, that's the body behind the rear wheel. Always get a look at the back side of the rear axle and suspension, and the body behind the rear axle!
And forget about 3x locked. People are constantly posting about problems with the factory lockers seizing up at this age. Spend 1/4 the amount of money on an unlocked, rust-free rig and add Harrop lockers. You can wire them to a factory Toyota locker switch and feel super cool.
I just sent you a PM with a question about factory lockers.
