Hello there my name is Achilleas and i am from GREECE. Unfortunately i dont have a HIACE

(i have a daihatsu feroza) a close friend of mine has an old HIACE 4wd and he wants to swap his diffs with an older version of HIACE wich has diff ratio 5.28 look the link above.

The diff code is G162 we are looking for, he wants that diff in order to fit a locker (lock right) does anyone have such a HIACE ? We would like some info and pictures of that diff because here its hard to just borrow a diff to take measurements.
Thanks a lot i am waiting for your answers.
