Courtney will run the #44 on his Mustang per the number he used in his early racing days.
With no certainty that he will join the BP Supercars All Stars Eseries for the remaining three rounds, Courtney and his Boost Mobile Racing Mustang may next be seen at Sydney Motorsport Park on June 27-28 for the long-awaited return to racing.
