I did some damage to the friction surface of my flywheel with a worn out clutch, and it needs to be replaced. I so far have had no luck finding an OE one as they have been discontinued, can anyone point me in the direction of a cheap aftermarket one, potentially of the lightweight aluminum variety, that will fit?

 

Try after market suppliers
Bavarian, Pelican, Turner

I have seen lighten flywheel available
or
take yours to a machine shop and have it repaired and lighten

It wouldn't be aluminum
