A-body hood scoop seals?

Who if anyone repop's the seals that go in the holes in the hood under the scoop? I think the hole size is 4.5" If i am not mistaken. Please let em know if anyone has a good place to find those seals, and please correct me if I am wrong on the hole size. I am going to put the hole in my duster hood if I can locate the seals.
Thanks, Matt
