They are all the same size: DX,LX, SE and EX, 4cyl and V6 on the sedans. The splashguards are only sold under one part number for the sedans, and since the front splash guards fit over the the side skirt, that would mean that the side pieces are the same size, just different colors. The only other difference is for 2001 they changed slightly in design, but still attach to the body the same way.
