Here is Jan’s mint 1978 Datsun 280Z body with a 1983 Datsun ZX engine in which he chose Traction Concepts Datsun R200 LSD Kits to convert his open diff into an lsd. Thank  you Jan for sharing your 280Z pic with the Datsun community. “Your unit is a great improvement over the stock differential.”-Jan A.,  Feb.7,2016
