1964 Ford Thunderbird Convertible
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.

The entire compartment is fully lined, and the jack assembly is concealed beneath a flap on the right side. The compartment is lit automatically when the deck lid is raised, and provides 11.5 cubic feet of space in the Hardtop and Landau models, 6.1 cubic feet in the Convertible with the top up.

All 1964-1966 Thunderbird closed models have luggage compartments that seem to be prone to having moisture inside them. This can be due to several things, an improperly adjusted deck lid, a bad deck lid seal, bent hinge, leaks around the trunk lock assembly, or bad drain tubes for the Silent-Flo ventilation.

Be sure that the trunk lock assembly is sealed properly with a good gasket. There is also a small plastic drain tube in this area that helps drain off water, thus preventing it from entering the luggage compartment. It must be in place to keep water out. But by far the biggest contributor to a wet trunk is the rubber drain tubes below the Silent-Flo Rear Vent which are supposed to direct any water that gets in the vents to an area under the car. When these split or fail due to age or abrasion, they will often dump water directly into the trunk!
