I've never been quite sure what it is that I have. I pulled some pieces from a yard and they went together. When purchasing them the center casing was marked as a R200 Z31 which was written on the casing.
.
The cradle was definitely off a 280zx, and as for the axles, I had no idea, just went around till I found something that fit the open center.
.
I have purchased a 2 way clutch type lsd for a r32. This physically fits into the R200, but am having trouble finding some input shafts to suit the lsd center. Will then have to re spline some axles to fit.
Cheers.
