Cheers Bruce for the instructions. I sits quite nicely on the bumper,no filling needed. Now there`s a slight gap all the way around but its uniform so i`m not too worried,after all its an add on and as you said,don`t want to spend money on respraying the whole bumper. I`m going to DIY it so less money the better! There`s no holes for screws to attach it on so what would you recommend? It doesn`t meet the bottom of the original bumper so can`t use existing screws. The only place I can attach the splitter to the bumper is to screw it is at the backside of the bumper at the arch,if that makes sense.Is sits snug under the bottom mesh to the lip of the bumper. I`ll put some pic`s on tomorrow to illustrate.
