Hi bigboy and welcome to TBN,
I know you are interested in the WR Long valve.
As Kenny explained, WR Long has kits that will fit your Kubota. I would personally go with the 3rd function solenoid valve that can be controlled with a rocker switch from your joystick handle. I did not get the complete kit but I believe it would contain the solenoid valve, the subplate, hoses, a joystick handle for for the FEL and brackets. You can contact Nelson Long directly for information about your tractor and what exactly comes with the kit. He is very helpful.

The reason I like the 3rd function electric over hydraulic valve over the diverter valve is that it's joystick operated via a bush button. All your FEL and
grapple controls are together and they all can work at the same time. A diverter will usually take the place of the bucket curl so that function is out of play while using the
grapple (whichever one you use to divert). Many guys prefer that method too and that works for them just fine. But if your tractor hydraulics have enough flow (probably not though) you can enjoy true 3rd function control of your
grapple with the thrid function valve. I found I can use my
grapple at the same time as my FEL curl and lift by "feathering" the FEL valve. That way the
grapple will also work at the same time.
Here is a video of my tractor working the FEL functions and the
grapple at the same time. It takes some getting used to, but it can be done. Since this video several years ago, I installed a larger gpm pump and now I can do it easier.
