You may need a new front right wheel arch to go with those boards - it looks damaged in the picture of the smashed X - but everyone is right, 2 lower panels that run along the bottom, 4 wheel arches, 2 aluminum RB's, and 2 long thin sections that cover the top mounting bolts -

I just went through this myself getting a used set, I was missing the right side lower sill which I got from a seller on Ebay from the UK ($120) - the wheel arches should be around $140 apiece I believe

Just to help you out here is the hardware you need to fit them (I paid about $50 for all from dealer)

07 11 9 915 093 -- HEX BOLT WITH WASHER ----- 18
51 11 1 944 537 -- EXPANDING RIVET ---------- 20
51 71 7 002 953 -- BLIND RIVET -------------- 26
51 71 8 267 301 -- CLIP --------------------- 4

I believe the #7301 CLIP only comes in Qty 10 packs so I had to buy a 10 pack, and one of the types of rivets as well - so I had to buy a few extra clips and rivets but I paid $50 for all hardware

Hope that helps
