I have two 314's for sale. One is a 5/16x14 thread and the other is a uni-loc. Both shafts are in great condition and are 12.75mm. The 314 with the uni-loc thread has a fairly new moori medium on it and the other has a brand new talisman medium. You can PM me or email me at cynion23@hotmail.com with any questions or to make an offer.
