The car is a 1994 but has a pre verto setup, MED Ultralight flywheel and all the pre verto bits. I've just changed the diaphragm from a Grey to a Orange and got the thing started but I've got a rattling from the clutch end. Goes away when I press the clutch pedal, still selects gears fine and has got rid of the grinding from reverse which I had a problem with.
Sounds like a release bearing problem, it was fine before with the grey and I haven't touched the two big nuts? Any ideas? Not sure how its set as I've lost my Haynes too

Thanks
