I was going to tell you to go search because its been covered plenty of times before, but unfortunately the search function on this site will not search "lsd" as its too short a term.
It has been covered over and over but your options are:
MA61
IS200
Those two cars came with factory LSD's, some 4WD hilux's may have came with LSD's in the front diff (which is usually an F-series).
There is a huge list of other places which make aftermarket units including:
TRD
Truetrac
KAAZ
Get out there on the internet and search, there are all sorts of different types of LSD's in 1 way, 1.5 way & 2 way variations as F-series diffs are in so many different types of Toyotas.
And as far as I am aware they are interchangeable between any other F-series setup.
