Sorry for the bad title! I don't know how else to put it. The Sims 3 horses are the bane of my existence. The tack is AWFUL and so I was very happy to find some awesome tack CC. The problem is that the Sim sits too far back on the horse for these new (smaller) saddles. So my options are to move the Sim forward on the horse (not even going to try) or to move the saddle backwards on the horse's back. I don't want to change anything except move it backwards (I assume that would be along the z axis?). Does anyone know how to do this and how difficult it is to do?

Actually I would prefer to move the Sim forward but I guess that is difficult to do and will mess up the animations?
