I watched YouTube videos...looks so easy (445 hood with 6 inch crack, still straight, just a hairline crack). After a few hours with a heat gun and hardware cloth, I now have a 445 hood which is stronger than original; however, it is not straight and flat and looks ugly.
At least it is concave (1/4 inch or so) so I can use body filler and paint...rephrase, my son when he is home from college...he is a better mechanic than I... Hind sight is 20/20 and I should have left well enough alone or gone the Ebay route.
