why dont you cut the fender in half from top to bottom and pull out the amount thats its off on each side. (ie, its off 1" left and 1" right then you would section 2" from the center where you cut it from top to bottom)
the thing with moving the lower half down or sectioning it vertically is that i dont want it to look like it has skirts and i dont want to change the shape of the wheel opening too much....but thanx for the input so far i appreciate the time u guys have taken to post on this....
