I am trying to confirm the correct part number for the ignition coil on a 1964 1/2 D code 289. In my April 1965 dated parts catalog is says it is B6A-12029-B. However, I thought that I read somewhere that it uses FAC-12029-A. In Bob Mannel's book, page 4-48, it shows a 1964 Comet with the FAC coil number. Can anyone confirm which is actually correct?
