Holes to plug up

[Redbird]

I guess all "A's" get a little warm inside, but what do you plug the holes up with? I pulled back the rubber mat and there are a couple holes, one to the right of the starter button and one to the left of the steering column cover. There are also two just opposite on the passenger side. My mat had holes punched and over these holes, but you can see daylight thru the holes. Also can you seal the pedals, etc any better?
