Just pulled this outta the 180, was told it was a Cusco but looks identical to the Nismo diff in the link below
http://www.frsport.com/Nismo-2-Way-D...D_p_10276.html
It comes cased from a '96 180SX with 6 bolt halfshafts which I can include if needed for a few bob extra
Very little knocks or noises from the diff and locks up sweet when you want it to, looks to have decent oil in it too
€350
