Tuscan/Griff GKN Diff id please

[cts]

Hiya, bought this a while ago, with other stuff, gkn diff, it has the following nos on it: 12HA 016 017 49X13 GKN C95 DZC, ratio I think is 3.7 looks like quaife internals?, do they all run quaife internals?, so is this std or a special, thanks for any help

Cheers Tom.

Not sure on the coding on mine, but the ratio sounds the same and my gkn also has quaife internals..
