1966 Ford Thunderbird Body Styles:
Hardtop, Town Hardtop, Town Landau, and Convertible
The Town Hardtop and Town Landau are both new, and would be
offered only in 1966; the Landau is retired this year only
Over the years, there has been considerable confusion over exactly which
models were offered for 1966. This is because two new model names were
used, one was retired for one year only, and people generally don't understand
what defines one model from the next. So, this is our attempt to provide
clarity to the issue.
HARDTOP (Conventional Roof)
Body Serial Code: 83 Body Style Code: 63A Color Shown: Honeydew Yellow (paint code L)
This model was the base Thunderbird model for 1966, and has the traditional
Thunderbird roof line with triangular-shaped rear side quarter windows.
It includes the standard emergency flasher system mounted on the map light assembly, with one on/off toggle switch and one
red "FLASHER" light that flashes to indicate system operation.
There is no overhead roof console in this model.
TOWN HARDTOP (Blind Quarter Roof-Painted)
Body Serial Code: 81 Body Style Code: 63C Color Shown: Candyapple Red (paint code T)
This was a new model for 1966. Note the difference in the roof line between
this model and the one above. No rear quarter windows were provided on
the Town Hardtop, and no vinyl roof was provided by the factory, although
there was a dealer-installed vinyl roof option available.
This model featured standard Safety-Convenience Control Panel with the
overhead roof console and warning lights, molded headliner panels, and
a console-mounted vacuum door lock control.
A black textured finish appeared on the floor and roof consoles.
TOWN LANDAU (Blind Quarter Roof-Vinyl with S-Bars)
Body Serial Code: 87 Body Style Code: 63D Color Shown: Ivy Green
Another new model for 1966, the Town Landau replaced the Landau for this
one year only. Note the difference between this model and the Town Hardtop:
the Town Landau features a Levant grain vinyl roof in Black, White, Parchment,
or Sage Gold with color-coordinated S-Bars.
Inside, the Town Landau has the same standard equipment and features as
the Town Hardtop, with the exception of the floor and roof consoles have
a simulated woodgrain appearance, as does the steering wheel (without speed
control), and both door panels have woodgrain inserts.
The designation "Town" identifies only the rear quarter roof line;
the designation "Town Landau" requires the additional trim (vinyl
roof, S-Bars, woodgrain,etc.) that are unique to the Town Landau only.
CONVERTIBLE (Conventional Roof Styling with Folding Top)
Body Serial Code: 85 Body Style Code: 76A Color Shown: Silver Mink (paint code E)
The 1966 Thunderbird Convertible retained the traditional roof line with
triangular-shaped rear quarter side windows, similar to the Hardtop model.
The power-operated folding top retracts into the luggage compartment.
This would be the final year for the factory Thunderbird Convertible model
until 2002.
The Top Control is mounted on the floor console in the location where the
Silent-Flo Rear Vent control is located on the other three models. The
emergency flasher control and light is located on the map light assembly,
as per the Hardtop model (click link in Hardtop section above for image).
The Town Landau was the best selling body style for 1966, followed in order by the
Town Hardtop, Hardtop, and the Convertible. There were no special limited
edition models built in 1966, and 1966 would be the final year for unitized
body construction for the Thunderbird during the classic era.
The Town Hardtop was a 1966-only model, and would not be used again. The
Town Landau would be brought back as a mid-year model for 1977, with a
high level of standard luxury features and would continue for several more
years. Ford considered calling the 1969 Thunderbird Tudor Landau a Town
Landau, but that model name wasn't actually used, despite early ad mock
ups that referenced it. A Town Sedan was also planned as a 1968 Thunderbird
Fordor model, but it also was dropped before production.
