As far as I know these hood latches aren´t reproduced yet but you often find them on ebay in different conditions, ranging from mediocre to bad... Here´s the 68 hood latch shown on it´s own (it´s an used one after zinc plating, correct would be phosphated):
front view (equal to the 67 style):
rear view (different from 67 style and will fit 68+69 hoods only but 69 style will show a different handle and a different valance support - the latter one not shown on this pic):
