Hilux are a top choice but once you shorten them,
leaf spring mounts to suit right stud pattern mods
is 2000+aud depending on purchase price and place
doing the work for you or doing it yourself.

Bluey H190 un-shortened + Jap H190 LSD is better
as Rotary peeps bust the strong 177.5mm & inch
mazda rotary diffs and go for hilux or 9 inch.

Rotary diffs with 4.875 centres are stronger than H165
metallurgy/quality is Nissan-like but not up to turbo 13b
torque or abuse for long before they give up the ghost.

I can get the LSD units to fit the H190 bluebird which has
correct stud pattern 4 x 114.3mm & bluey diffs are cheap
and 1450mm vs 1305mm for H165 so no shortening required
if you have the right offset wheels 40-45mm is nothing.

So un-shortened bluey diff $120 at most wreckers like pickapart
and LSD unit 950 from Japan & modded mounts around 1300 total.
Alloy carrier option also available for H190 for lightweight.
