The picture was taken March 31, 1967. The spoiler was not really available in '67 but there may have been a few made by GM that were given to a few select racers. In some instances, some racers made their own. Bob Tucker, who built Joie Chitwood's Camaro, told me he was supplied with a blueprint for the spoiler prior to Daytona (late January '67) and he built it out of wood using the blueprint as a guide for the dimensions.
