motor / part in question - hilux diff

problem - I want to buy an LSD for my 1983 hilux (G series diff I think?) but I am unsure of what to get, I don't want a factory LSD as they are pretty average, I want something more along the lines of my TRD 2 way in my T series in the 86, is anything like this available for this diff? And no I don't want a tru trac
