As a result of a long drawn out frame-off restoration on my '70 SS, I cannot locate the jack. I have the base and the hook though. Can any one point me to some leads on locating one, i.e., what other cars (Chevy, Buick, Olds, Pontiac) is the '70 Chevelle jack associated with or is it one of a kind? It might be specific to a '70 year model as my '71 Chevelle jack is certainly different (hook has pin on it and is not removable).
