Why it matters

For the 1969 Trans-Am season Ford had Kar Kraft build Boss 302 race Mustangs and ran them through both Shelby and Bud Moore. Only three Boss 302s were prepared by Shelby, and the car offered at RM Sotheby's is described as the only surviving example.

02Production & history

Production

Every figure says what it counts.

What is counted	Figure	Basis	Status
Total model productiononly one of the three Shelby team Boss 302 Trans-Am cars (chassis 628) survives, per the auction catalogue	1¹	Surviving examples	Independently researched
Total model production1969 team cars built ('one of three')	3^1,2	Factory production	Factory reported

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Unlike earlier seasons that Shelby handled almost alone, Ford used Kar Kraft's engineering for the 1969 contender, which also let Bud Moore field two cars. The Shelby team received three Boss 302s built by Kar Kraft; the lot car was the second of the three. During the season two of them (627 and 629) were written off and 628 emerged as the only surviving team Shelby Boss 302.
