kldiet, did you run the engine with the belt off when you were getting ready to do the SC change? Any change in the noise? Sorry your work didnt pay off. But you should be able to recoupe some of your money by selling your used SC. Didnt the replacement SC come with a clutch? I thought it was part of the SC. That should have eliminated the clutch as any issue. You are correct, the two SC's would be VERY unlikely to have the same exact problem. Keep up the fight, you will get it resolved.
