Trust me if you don't want gaping gaps/holes, just go for the real deal.
I was debating whether to go for the replica Middlehurst ones when I bought mine. And i'm so glad i went for the originals.
The finish is soo much better so less time needed for spraying/prep, and they fit spot on. No dodgy gaps. They have a thin foam gasket which fits in between the bumper and the skirt. Comes with all the necessary hardware; bolts, nuts, washers, etc. And all the templates for drilling the holes.
Plus the replica ones weigh sooo much heavier!!!
At the end of the day you pay for what you get...!
