I am looking for the piece that screws on top of the posts in order to hold the racquet in place on a Gamma X-2 Stringer. I seemed to have misplaced one of mine and was wondering if anyone had a spare one or something... If not, do you guys know what I could use as a substitute? Maybe another piece that functions similarly that I could buy locally? If so, eMail me at ShingCTse@hotmail.com Thanks guys.
