Is your 69-70 Shelby hood bowed? Most likely it is - especially if yours has a high-heat generating big block underneath it. The combined forces of spring moment, thermal shock, and age have taken their toll on that fiberglass - eventually resulting in that disturbing gap that you're sick of looking at. If you want to permanently de-arch your hood so it matches the curvature of the fenders, I can make it happen - *even if the topside of your hood already has nice paint on it (*in most cases but each hood will have to be assessed). There's a whole lot more to fixing this than these few photos reveal. And it ain't cheap. It requires major surgery - but when you add some stretch-formed structural metal inserts in there while in the process, you end up with a stronger hood, resistant to future bowing, and perfectly aligned with the fenders and cowl just like A.O.Smith intended. The underside will be as factory - all of the oozy looking cemented joints will be mimicked (but with high-strength fiberglass resin with additives), rear vent screens re-epoxied, outer edge painted with your body color, and new flat/eggshell black paint with the correct feathered edges around the perimeter. Now you can quit screwing with those old wives' tale remedies (unhooking the springs, piling on weights, etc., etc.) that DON'T WORK - and fix it once and for all.
