By way of illustration my Wolf sport valance with GT aperture, accomodating Cain's prototype
overrider mounts and added bracing bar behind. Latter really stiffens up the otherwise floppy OE mounts. If you zoom in bar can just be seen through aperture grill.

I believe pic above was taken before I needed to replace OE rad with ally SiFab one but the valance covers both anyway. The aperture specified is the only one that matches full width of grill above.
