Coy Duke (Byron Cherry) 1982-1983 season of The Dukes of Hazzard), the replacement for Bo, was another blond-haired cousin who moved to Uncle Jesse's farm along with cousin Vance (Christopher Mayer) after Bo and Luke left Hazzard to join the NASCAR circuit.
Fictional character biography
Coy Duke, along with cousin Vance Duke, had previously lived on the Duke farm until 1976, before the series had started. Coy had been a test driver in Detroit, before he and Vance came back to Hazzard in 1982. Coy was a lot like Bo, with blond hair, and falling in love with various girls during their adventures. Coy loves action, and, like Bo, he usually is behind the wheel of the General Lee. Together, according to Boss Hogg, they "make Bo and Luke seem like choir boys."
Being written out of The Dukes of Hazzard
Both characters proved to be unpopular with fans and were written out after 19 episodes. Cherry and Mayer replaced John Schneider and Tom Wopat while the latter two were in contract negotiations. For more details on this topic, see The_Dukes_of_Hazzard#Bo_and_Luke_leave_the_show.
