I just installed the spin on filter kit from Scar59. Everything needed was included -- replacement gaskets, bolt, and a new spin-on filter. It took me about 30 minutes (mostly prep time -- rags, bucket, tools, etc.). When you install, make certain to use the correct thickness rubber gasket (this is positioned on the truck portion, not on the new adapter you just bought). Instructions came with the kit. Of course remember to lift off the wheel well engine splash guard for easy access. I found it also helpful to turn my front wheels to full left for even easier access.
