Wrong numbers.
Assemble a wire brush, a strong light, a strong magnifying glass, and a pair of "young eyes"
Turn the carburetor such that you can read the word "Holley" on the bowl. Note that to your left is a boss into which is screwed the fuel inlet fitting. Clean the side of the boss that you can see with the wire brush, apply the light, glass, and young eyes; and you should be able to read (maybe), the word "LIST" followed by the carburetor identication number.
Google should then give you an application.
Jon.
