sounds like the problem my brother had on his old EB, although he also had a slight rattle when the clutch pedal was up. The bearing you mentioned rings a bell but his clutch forks were tending to bend/break as well. Get it checked out immediately, it cost 2 new gearboxes, also in the engine bay check around the fire wall were the clutch cable goes in - it tends to fatigue & crack, putting more stress on the clutch pedal assembly. I would recommend all manual Falcon drivers do this because its so common that the local Ford dealer in Canberra has firewall reinforcement plates on the shelf.
