If you knew the answer beforehand then why did you ask the question? By doing that people will learn to not answer your future questions.
Below are the photographs of two original 1966 firewalls. I am only assuming you are talking about an early car, you didn't say. The first is a Dearborn A/C coupe. Those hoses have NEVER been out of that firewall since installed in March 1966. (The extra pair of blue and red connectors are for the C4 wiring. The wires are the lower left are non-factory cruise control wires.) The second, with dimpled sheet metal, is a non-A/C, 4-speed, San Jose Convertible (no C4 wires). There was a knockout formed in the metal but it was not knocked out unless you had A/C. Ford was not going to do extra work and add extra parts if you didn't buy A/C.
BTW, tell me how I was wrong other than the dimples are only 1 7/8" apart.
