no 65 is 100% different-- look at the hood to fender, it's nearly flat where the 63 & 4 have a pronounced curve downward into the hood.
however, i'd say that it's close-ish that you might'n mayhaps work it out if you got creative. but unless you're a master body man and fabricator, it's gonna look butt-- the headlight bezel would be the least of your worries in matching that stuff up.
