Modified parts to fit Splash guards (Aero covers) as per other forum members:-
If you do not have a rivet nut installation tool, ignore Items No.23 & 24, & just order another 4 of the plastic spreader rivet (Item No.25.) making a total of 8 quantity of Item No.25 to purchase. Forum member "Reggie Enchilada" has used this on his car & done 140mph with no problems!
