If Its 14 It Should Fit Thread Wise. Pilot May Be Too Big But That Can Be Taken Down. Ive Owned Many Joss Cues That Were 14 Thread. Few 3x8-10 And Now They Do Some Radails. If Its Piloted Its 14
''IF'' the pin is totally threaded 5/16x14 it should work unless the pilot is too big!!if the pin is J.P.'s speed pin it wont take a Joss shaft without modifying the pin(which might be difficult to do)
