Uh, I don't know anything about a carbon fiber driveshaft, but thats sucker's gotta be $$$!!! I'd go ahead and get the aluminum one from a 93 Mark VIII. It SHOULD be more than enough for the average joe street racer. (I can't believe that's the first time I've actually made my nick-name pun. Many other have though.
) If you want something a little better, you could give Dennis Reinhart about a Metal Matrix driveshaft. I don't know anything about them though.
