Well, that will work. The correct ("official") way to do it is to remove the overriders, loosen the bolts on the hinge boxes, and move the pivot point up in the slot, then re-tighten. I think it's the front bolts (hinge bracket to outer box) that has the vertical adjustment, while fore-aft adjustment is available in the hinge bolts themselves (accessed through holes in the sides of the boxes).
