Just pulled this out of my 13, its got maybe 5000 miles on new seals and bearings and is very solid! 4.08 Gear Ratio and VLSD from a Z32 with output shafts stuffed into an R200 S13 housing with an R32 cover (keeps the diff cooler). All you gotta do is add gear oil and drop it in!
$225 Picked up! COME GET IT!
