I too wanted to keep my overriders. Initial thoughts were fitting full bumper tubular mounts and adapting overriders to fit them through holes in Wolf full width sport valance. Also lowering number plate box.
After Cain suggested he can modify standard mounts to accommodate overriders and his valance, thoughts have moved on. Maybe keep number plate box as is but add GT aperture to valance which should match grill above width wise.
