    Okay so I have seen a few post over this but they all seem to be a little over the place so I thought I'd ask about what I found here. I have a 1983 datsun 280zx non turbo.

    So my 280z rear diff is pretty much toast. I'm looking at a 240z diff to replace it. Does the 240z diff fit the 280z? (Is it bolt on) If not, how difficult would it be to make it fit. Thanks.
