You are never, ever going to find a perfect match. Just think about how the titles were made: they were almost certainly done up with Letraset or a Linotronic (or something like that), possibly shot with a process camera to make a 'negative' PMT, and then filmed with a Dykstraflex camera. Any one of these steps could change the kerning, the weight of the type, and introduce spherical (or anamorphic?) abberations.

So, the best way to get an exact match is to start with something damn close -- the aforementioned Franklin Gothic, say -- drop everything into Illustrator or CorelDRAW (as I mentioned before), and adjust nodes by hand. Not difficult at all. Just a bit time-consuming. Assuming you've got Franklin Gothic, of course.
