Yep, Southbend is good, Valair makes a decent one as well. If only lightly chipped, a single disc will do. I went to the brass/ceramic type clutch many years ago. They are aggressive and don't slip, but don't expect them to be smooth when letting the pedal up. I used to wear out an organic clutch every year on the K-30 hauling hay out of the field, and went to these. That clutch has lasted for years.
