Van Pelt has a good section at the back of his parts catalogue that lists all the possible problems re clutch chatter. suggest you document your starter bendix and flywheel ring gear relationship so you can confirm any replacement flywheel will put the ring gear in the same place. See my comments above. If your throw-out brg is not just where it needs to be and centered you will sure have pp problems. Suggest you get that right, but you will have to take the engine out and trans to get to it of course.
