Can anyone help me?

I currently run a 3 bolt clutch/flywheel... Yesterday we fitted a recently machined 6 bolt flywheel/clutch. Started the car had a bad rattling coming from the bellhousing area. Took the box apart again took the clutch off and started the car off the bellhousing. Noise still there. Took the flywheel off and put the old flywheel off and the noise goes.. The new flywheel looks a bit thicker then the old one so does that mean it needs a spacer or something? Or is it out of balance? I'm stuck on ideas here and where to go next. 6 Bolt manaul flywheels are so f**k hard to find these days but I don't know if it's worth spending more money on the f**k flywheel to get it balanced..

Ideas? Cheers.

Just drill and tap the old flywheel......thats what I did in my EA. Didn't have any probs.

You should check if the ring gear is loose. I have heard of them rattling before.
