I did not use a system . Just modified it inside by taking the bottom panel on mine out. Then used a small peice of plastic to make the gap almost non existant between the bottom of the stick and the base of the unit.
Then used the Virtual H shifter for the shifting.... Not a wonderful way but couldnt be bothered to buy a FFB Joystick
I have done it. Its not bad with Virtual H Shifter. I did not have a FFB Joystick, so I modified my MS Sidewinder (non FFB) to become stiff and to hold in place. Worked well im pleased to say
