hood scoop question

They mount with two chrome #10 screws. They have an oval head but the head is smaller in diameter than a standard oval head #10. I actually found them local at our Ace hardware in the chrome screw section. I was originally looking at stainless. The screw was the right size but the head was too large in stainless.

The scoop itself has tabs with holes for the screws. They require fold over clips on the tabs for the screws to thread into.
