You can have these Louvers custom made to match the pattern of your hole in the wheel well. I bought these louvers to place them in 2 positions. 1 as far back into the wheel well and I mounted it on the outside because there is no interference with the tire. 2. The one outermost has to be mounted inside the aluminum panel to avoid tire interference. The tire will kick up dust and debris so they should vent from the top down and block dust, dirt and rocks being thrown up from the tire tread. This along with your screen, should keep the footbox and header collector clean longer. You can mount them on the inside on top of the screen. I did not use a screen, because that'll just get clogged with mud. Mine is a West Coast Cobra. It has no wheel well material at all. The aluminum you see in the photo is non-standard. I have no heat shield. I think I may need to look at making one.
