Well the firewall is all buttoned up. I filled 45 holes. About 20 small holes, 20 quarter size holes, and five large holes. It is not perfect but I am pleased with how it turned out. With a little sanding and a light coat of filler it could be great. The best compliment I got was from my wife who didn't believe it was our car when she saw the completed picture below. Thank goodness old metal is thick otherwise I could have never patched the firewall with my inexpensive flux core welder.
