Le Mans factory hardtop on CSX2142, a '63 289. Note the gas filler on the roof. The original filler is on part of the rear deck that's covered by the hardtop, so they ran a hose up to another filler cap the roof. I saw one of the 289 Le Mans prototypes race at SIR in the Historics one year...very cool cars! I believe you can get these from some of the Cobra replica manufacturers.
