Ken, yes, I think that is the correct name. We do have the part and it is indeed bad. I saw them take it off and put the new one on.
I wish the metal were just "almost powdery." However, I can remember seeing one metal part that was probably a half inch long, maybe a sixteenth or eighth wide. I can't rememer how many there were, but I think that was the biggest one. The Nashville shop said they were from the clutch.
