Sorry for the late reply and thank for the info. The only reason I'm calling it a 2way nismo is because it was advertised as it all tho I must say its does look very similar to z31 turbo lsd.
Greetings everyone.
I have a nismo 2way LSD that I would like to attempt to install in an R200 3.90 from a 1981 280zx (if that is even possible) and use the 29 spline inner stub axles that came with.
