Steve is right you should have the directional slicers which means you can put the lefts (LH) front or rear, same with the right. To tell wheather you have directional slicers with out removing the center cap just look to see if there is a small recess some where around the edge of the center cap (this is to aid popping off the center cap). If you don't have them then you have directional slicers. If you do then you have non-directional slicers. I have posted here before as to the effects of putting a directionl slicer on the wrong side since directional & non directional wheels look to be identical other than the fact that directional slicers will give you the flat of the 12:00 spoke always facing the rear of the car.
