AMT made kits in 1/25 scale in 1958 of the 1958 Thunderbird. Monogram made 1/24 scale models of the the 1958 Thunderbird starting in 1964 with reissues in 1974 and 1987. Monogram released an Elvira "Mistress of the Dark" 1958 Thunderbird in 1988 and a Richie Valens "La Bamba" 1958 Thunderbird in 1989. It is intersting to note that the Thunderbirds used in both the Elvira and La Bamba movies were 1959 models. Obviously Monogram did not think anyone would notice the difference.
