I've been told ARB makes an air locker that will fit my 1995 KZJ78 by a reputable shop. They make one that fits an 8" rear end, which my KZJ has. Not sure what the LJ has. Other option is to try to find one of the E-lockers that toyota made as a factory option. Those are hard to come by though, people tend to hold on to them. I'm looking for a rear locker for my KZJ as well.
I can't remember: Is the rear diff in the LJ78 a limited slip, or is it an open diff?
Most are open.

The front differential is interchangeable with the 1990+ heavy duty 70 series, and the 80 series. A number of people have installed locking diffs from those trucks into the 70 series Prado's (1990+). I plant to do this when I find one close/affordable. There are some minor modifications to the diff housing that are necessary to adapt the locking diff, but everything else fits/bolts fine.
I think the Prado 70 series rear differential is unique from some of the other Toyota 8" ones. So I think that finding a OEM one for the Prado 70, or buying a specific aftermarket one would be the way to go there.
Rear differential is the same like 90 series, 8", you can find it with original e-locker. The LJ78 usually works with a ratio 4:88 and the KZJ78 manual gearbox 4:56 and with automatic transmission 4:30. Usually the kzj/kdj 90/95 series works with 4:30.

Right? I cant imagine them being lighter duty than a 4runner or fj cruiser and they have them. Silly
That's just rubbish. Suzuki Samurai run lockers. Your LJ78 is perfectly fine with lockers.

The front axle of the Prado 70 series has the same differential, axles, birfields, knuckles, spindles, hubs and brakes as the heavy duty 70 series. Only thing that's different is the housing (to suit coil springs instead of leafs) and gear ratio. So you're right, it's definitely not light duty.
The rear axle has a 8" diff as opposed to the 9.5" of the heavy duty 70 series. And it's a semi-floating design, not full floating. Yet, it's still a tough piece of kit for the most part. I've used my rear e-locker countless times and not had a problem. I've also towed a camper for years with my truck. No issues with axles or diffs.
All that said, locker's need to be used properly and in the right situation only. Abused enough, things can always break.

Did yours come with a factory e locker or did you out it in? Really would love to find an e locker for my KZJ78.

It came with a factory one. I LOVE it.
I'm also wanting to buy a rear locker for my LJ79, and I have researched into this quite abit. As GTSSportCoupe said our only options are either the factory e-locker or a specific aftermarket. E-lockers are harder to get by so I looked at the various aftermarket options. The most one I liked, and the one I'd want to get, is the TJM pro locker. I like it's design better than the ARB one, mostly it's actuation which uses a sealed pneumatic cylinder. Downside for me is it's harder to get in Europe so it'll be more expensive importing it.
I was just looking at those for my truck as well. They fit a KZJ78 apparently. Looks pretty solid as well and a decent price (here in Canada anyways).

Do you have a part number?
168PL25
TJM Pro-Locker fits Toyota 8" 4 Cyl, V6 & High Pinion, Air Actuated (168PL25) • $940.50 is the one for the KZJ78. It has a fitment guide on the page as to which models it fits. but it's an 8 inch high pinion.
