Great parts. I like how the case already has the seal and the bearing installed. Have not installed yet, but should go smoothly.

Very good kit, has everything your need and goes together easily... however the Speedo gear hold down screw is threaded for an M8-1.00, but the OEM housing is threaded for 5/16-18. The housing is aluminum, so it could be very easy to cross thread that bolt if you don’t immediately realize it’s not the right size. 5-16 & M8 are very close in size.

This kit arrived quickly and was complete. It has all of the hardware necessary for a complete install. Black silicone gasket material (RTV) is recommended and Blue LockTite. The RTV and LockTite are not included, so you'll have to have some on hand. We removed our transfer case from the vehicle, which made the install fairly easy. (watch a YouTube video for helpful tips on separating the case). The kit fit the NP231D transfer case perfectly. We haven't run it yet, just ordered our new drive shafts, which you may need for your project as the T-case output shaft is shorter than the stock configuration.
