aluminum flywheel/replaceable friction surface?

["Craig Halsted" <chalsted@adelphia.net>]

I've read about replaceable friction surfaces on aluminum flywheels and
wondered if anyone has any knowlege of this process- dealing with an
aluminum roadster flywheel that has a friction surface similar to clutch
disc material which is riveted to the flywheel... can you buy a replacement
friction surface for this type of flywheel? any input/advice appreciated.

Thanks-
Craig
