Australian Ford Mainline Utility
In Australia the Mainline name was applied to a locally developed 2-door coupé utility version of the Ford Customline sedan from 1952.[9] The Mainline utilized an imported Ford V8 convertible chassis [10] with the large X-member for additional load carrying strength.[11] It sold alongside the Australian built Customline sedan, with both given yearly updates until production ceased in 1959.[12] The coupe utility slot in Ford Australia's lineup was filled by the first Ford Falcon utility the following year. The Mainline Utility was powered by an Australian produced version of the Ford side-valve V8 engine [13] until the introduction of the OHV V8 in the redesigned 1955 series
