Need help with UCA bushings

RedFish said

Since I'm no alignment expert I sure would like some pictures and more info here. My querry is just how far do the offest bushing throw the upper arm from its original postion and in which direction. Descibed in approx. inches rather than degrees, in or out and forwand or back rather than positive and negative.

I don't have pictures, but what is happening is you are moving (or attempting to move) the upper balljoint toward the rear of the car. Each degree of caster means moving the upper balljoint rearward 0.180". With the stock bushings, there is only enough adjustment to get the factory recomended caster. If you want more caster you need the bushings or the tubular upper a-arms or you can cut and weld your upper control arms (but I don't recommend cutting and welding them).
The added caster makes steering effort a little more (this is more "road feel") and makes the steering want to return to center after turning.
