John Deere 4105

Does anyone know the part number to replace the factory FEL lever knob with the Ergonomic handle grip like shown?

That is a joystick for use on a loader with 3rd function hydraulics. My 4105 has a 300CX loader an was ordered with extra hydraulics for the loader to operate a grapple. That joystick has a thumb-operated button to open and close the grapple cylinder. I am not sure if you can order the joystick separately.
