That is what im trying to do, find a Sprinter T50 box.
But no-one seems to have any.
I have found a modified supra box with 4AGZE bellhousing but the input and output shafts are different sizes to my old gearbox and i dont want to have to change the clutch and tailshft too.
I also found a J-Spec box but it was $700, that seems a little excessive, is there a difference between j-spec and Aus-spec boxes?
