NISSAN doesnt have a kit for it...

You need these adjust washers (shims) that are highlighted GREEN & RED

I put together a kit that includes all possible shims...

You know when you've been tangoed

Central20 Final Drive seems considerably cheaper than the $850 quoted

Pinion Shaft Crush Sleave $9.50
Pinion Nut $5
Front Pinion Bearing $34.95 (Item & price from 350evo's site)
Rear Pinion Bearing $54.95 (Item & price from 350evo's site)

Couldn't find the Front Pinion Bearing & Rear Pinion Bearing on PNP's website, I guess they can supply them OK or that I just missed them

So about $1085.65, plus whatever shims. Anything I've forgot? I'm asuming you can reuse all the driveshaft, halfshafts, & pumpkin nuts & bolts?

Hmm, i thought the ring and pinion sets where more like $500, not $800.

This is an old thread but I'll throw this in. Here is a great write up on a lsd and 3.9 final drive installation. It is in the DIY section. https://my350z.com/forum/engine-drivetrain-and-forced-induction-diy/233536-cusco-rs-and-3-9fd-install.html This should help out. The prices of 3.9 final drives are lower now because back when this thread was made I think there was only one company that made the 3.9 final drive. Now Central 20 is doing it and they are great and cheaper.
