If your reason for wanting a steering stabilizer is to remove wobble or shudder from your front end then, as John has questioned, you might want to confirm that all of your steering linkages are in good order first.
I have a return to centre (RTC) steering damper on my 2010 FG. As much as it would probably reduce/eliminate the above issues (should they exist), I see it's primary function as "wrist protection" when using the truck in off road situations, where the steering wheel may jerk suddenly if one of the tyres hits something.
The bracketing on my steering damper is pretty simple; one connection on the steering rod and another onto a fixed point on the diff. If you cannot source suitable brackets for your FG, they would not be difficult to make yourself (or to get a shop to fab some up).
Here is a couple of pictures showing my setup, if that is of any use...
