I just went through this on my rig. There are two different sizes (diameters) for the speed gear, so two different sleeves and gaskets that seal the speed gear to the sleeve. When I searched you could get a similar gasket seal at Fastenal but I ended up buying at Motor City K5.

You also need an o-ring that fits around the sleeve and compresses the seal to the transfer case to seal sleeve to transfer case. I took my sleeve to the local plumbing store and found one that fit. I attached a photo. The sleeves don’t always come with the sleeve when you purchase them.

I’m assuming you have the sleeve but just need the seals. If not, the sleeve is speedy but available at Torque King.
