Clutch kit recommendation needed

Once upon a time I had a '67 Valiant with a '68 340 on a '67 factory 4 speed. One night taking my girlfriend home about 2am, I realized how late it was and while travelling along at 60 in 4th, I stepped on the gas, heard and felt a "bang" and later discovered she'd spun the hub out of the oem 9.5" clutch. Moral of the story? Put a 10.5" clutch in and never have a problem.
