First, welcome aboard.. If that clutch came apart like I think it did, I think I'd be checking for proper alignment of the input shaft and the clutch. Of course you don't say what kind of service the previous disc saw.. was it drag raced / road raced / just a cruiser? When they install a new clutch kit, don't forget the input shaft bearing/bushing.

Here's the page for Ford Racing clutches, Ford Racing Performance Parts 2014 it doesn't give any real load ratings but if used in "normal" applications I don't believe you should break it easily.
