This SportRack cargo box does not support bare roof mounting for a 2008 Honda Fit. You will require a roof rack system with crossbars and mount the box to the rack system. We carry a SportRack all-in-one roof rack system that will your 2008 Honda Fit (5-door), available as Product #40-1077. Once you have the rack in place, you can mount the cargo box to the rack using the SportRack U-Bolt Kit, available as Product #40-1041.
