Throw Out Bearing FILETIME=[EE4ECB60:01C10966]

While going through the most recent M*$$ Catalog, a friend pointed out
the throw out bearing that they offer rather than the bushing. Has
anyone used the bearing? And are there any problems with it?? The
catalog states that the bushing is N/A, which is odd as we just bought a
new one last week from our parts supplier in Ft.
