Jim, they made the hood weak in the middle so the dang things would fold in a front end collision . Problem was , NO ONE greased the hood hinges ! So....................., what happens , the hoods folded anyway ! Then folks like me started manufacturing Chevrolet Hood stiffners to folks around Houston . OH Man, I couldn't keep em around back in da day . Gee, I wish it were 1976 again an I was still in Houston makin all da mo mo !!!!!!!!!!!!!!!!!!
