It is a VLSD from a JDM S14 with six bolt output flanges. It ran perfectly when it was on my car. It is just the VLSD and flanges, not the whole pumpkin.
It is a great upgrade for S13 or S14 open diff cars.
The reason for sell is that I have upgraded to S15 HLSD.
Pretty sure its a matter of taking your old output shafts out, maybe getting new oil seals there, unbolting the open diff, make sure you keep your shims organized! put in the new diff, new output shafts and your set.
That’s a killer deal. They go for $300 US easy on Ebay, without the pumpkin. Perfect for someone who doesn’t have or want to spend the bling for a clutch type.
