I have three R200 LSD's (non-viscous) from Japan for sale. They are exactly like the 280Z differentials. Comes with 4.375 gear ratio and case included. I'm asking $450 obo. for the NISMO version and $350 obo. for the regular one. They are all ready to go without overhaul. Please compare the prices to what Arizona Zcar is asking. I'm in Southern Cal.
