I'm a bit lazy - so I'm pointing you to my web site where I documented this -I cannot tell you who made the hinges, he wants to remain anonymous, but I can tell you he used a 50 ton press brake. restoring hood (https://www.wbnoble.com/cars/36_Cad-Hood/36_cadillac_hood_hinge.htm) I made the chrome trim spear and some other pieces as described there also. ask me if you have questions.
