I also had the problem with the short bearing I got with my last kit, I even had to move the lock nut on the adjusting rod rearward to get more travel and still wasn't enough. I just got a Federal-Mogul 614037 bearing which is the exact one that I originally had before the first clutch change.
Did you check the run-out of the crank with tranny register bore in the bell-housing and also the rear face of the bell-housing? Mine was offset enough to have to use 21thou. off-set pins.
