While at Alan Mann Racing Bailey designed the bodies of a pair of gullwing cars, used in the Gerry Anderson in 1969 science fiction film Doppelgänger constructed of aluminum, the cars were assembled over a six-month period on modified Ford ZodiacMk4 platforms fitted with Ford Escort engines and gearboxes.
At the end of 1969 Bailey penned the Alan Mann Open Sports Ford just before Mann wound up his operation in late 1969, this was raced semi-successfully in two Can-Am races during 1969.
