All 81-83 280zx with a 5 speed should have the 3.9 diff. I don't know of a good way of identifying it externally other then spinning it and counting the rotations. Ring gear will have 39:10 stamped on it.

Where are you located?

280ZX 81-83 Automatic all (3.545) (R180)

280ZX 81-83 Turbo - all (3.545) (R200)

280ZX 81-83 MT (3.9) (R200)
