Straight from the horses mouth:
Our Doubler™ twin stick shifter locates both of the shifters in the same hole in the factory location. One shifter will operate the NP203 and have Hi-N-Lo, the other shifter will operate the 205 with the stock shift pattern, 4HI-2HI-N-4Lo. Our twin stick shifter is heim jointed, uses urethane bushings for the pivot points, and comes with a floor boot and proper hold down rings.
and
Our NEW 3 stick shifter uses one stick to shift the 203 gearbox and 2 sticks on the NP205, allowing individual control of the front and rear drive shift rails. This gives smoother shifting characteristics and with the proper internal modifications to the NP205, will allow easy access to front wheel drive and rear wheel low range. This allows you to use the full potential of your transfer case for maximum maneuverability. Price for the 3 stick is $250 and includes floor boots and all the parts shown.
