Rear Lockers for D40 King Cab

Hi folks

Recently acquired a 2008 D40 (Thai) King Cab Cab Chassis STX Auto.
I'm contemplating rear lockers. I have looked at the air and electric lockers available. However I investigating Auto Lockers to cover all bases...may even be a preference due to cost and set and forget usage. Would probably also get an air or electric locker for the front at some stage.

Yukon Grizzly and Spartan make this type of locker for the Nissan Titan. Is The US Nisan Titan the same as the Navara D40?

Has anyone put a Yukon Grizzly Locker (YGLNTITAN-32) or a US Standard Gear - Spartan Locker (SL NTITAN-32) in their vehicles?

The specs for both these lockers are:
Ring Gear Diameter: 8.500
Cover Bolts: 12
Ring Gear Bolts: 10
Spline Count: 32
Dropout: False
Pinion Support: False
Rear Suspension: Solid
Are these the same as the Thai Navara diffs?

Reviews, experience, feedback or opinions appreciated.

Cheers
Brad

Ahhh...The Nissan Frontier is the same as the Navara is it not?

...mmm...better do a bit more research then.

None-the-less any info would still be appreciated.

I have a 4wd sysystems lokka in the front and love it. i would stick with the auto/mech locker in the front and and air/e locker in the rear.

Interesting...

Has anyone fitted an Eaton Truetrac differential to their Navara?
