I am getting my clutch put in next week and I know that I will need my flywheel resurfaced. How can you tell if your flywheel is finished or if it can be cut? I just want to make sure that I don't get hosed by the guy saying I need a new flywheel. My car has 78,000 miles on it and I am assuming it is the stock flywheel. What is the life expectancy of a flywheel and should I expect to have to buy a new one. Thanks for the help!
