I'm sure you saw a great improvement with a second bar. For future readers with an F53 chassis, you could do this with the expense of adding another sway bar system. Other than this form of increasing anti sway/roll, you have 2 basic ways to accomplish this and both simply increase resistance.
One is to replace the stock bar with a larger one (increase diameter) the other is to reduce the leverage on the bar. This means moving the frame link from the end of the arm, closer to the axle.
Ford built their bars with two holes in them. One at the end of the lever portion and another 3 inches closer to the axle. Moving the links to the inner hole takes 2 wrenches and 30 mins of your time. As discussed in the thread I mentioned earlier, the results are nothing short of amazing.
