If you bought a kit, there should have been gaskets / seals for the part of the inner fender that connects to the firewall. I don't see why a set made from tar paper wouldn't work just as well. I used weather strip adhesive to attach them to the inner fender. Here's a couple pic of my 1954, under hood and under the left front fender. Should provide some help with the sponge rubber, even though the 1947 - 1953 fenders are not exactly the same as a 1954 due to the parking lamp lenses....
