	Transistorized Ignition System A new Thunderbird option for 1964, the transistorized ignition system cost $51.50, and was promoted as providing a hotter spark to the plugs, which resulted in more uniform firing at all engine speeds, and significantly extended spark plug life. This system also reduced current flow through the distributor breaker points, which increased their life, and allowed longer intervals between ignition tune-ups. This system was not without issues, however, and many were disabled within just a few years. This option would be discontinued after the 1966 model year.
Thunderbird's Deep Well Trunk In response to concerns of inadequate space in the luggage compartment from owners, Ford introduced the "deep well" trunk on the Thunderbird in 1964. This was accomplished by relocating the fuel filler to the left quarter panel, and moving the fuel tank forward to a position just above and behind the rear axle. This created a shelf at the forward end of the luggage compartment, which houses the spare tire on Hardtop and Landau models, and the top pump, motor, lift cylinders, relays, valves, solenoids, and hydraulic lines on Convertibles. The spare tire is located at the bottom of the well on Convertibles, and contents of the luggage compartment are protected from soiling on this particular model by a spare tire cover, provided as standard equipment.
