How to install quick-steer on an '08 without breaking the steering cable: Drill a 6mm hole though the steering stop on the handle pole's top cast aluminum piece. The hole should be positioned where the turn plate hits the stop. Run a 6x25mm or 30mm bolt through it with a nut on the other end. You'll want to run one to two washers on either side. Run the minimum number of washers so that the plate just hits the bolt. Adjust steering to center and ensure steering solidly hits the bolt and nut before cable bottoms out.
Your handlebars will not pivot as far side to side, but the nozzle is traveling just as far left-to right as before. It is just that now it travels faster because of the quick steer.
An '07 pole and cable would give you even extra travel than this this option. Although, if someone comes out with a better steering nozzle that has a shorter arm, that would effectively give you more travel as well.
I will post a pic tonight.
