The outer bottom edge of the Mini is one of the more likely places to rust. As this is also not a flat piece of metal is also makes more sense to replace rather than try to hand bend a new one! Available for left or right side this piece is for MK3 L/H and later vans/pickups etc with 6 flute vents. TOTAL WIDTH OF PANEL 5" This panel starts at the outer seam and extends about 4" under the side of the car! .
