I have a YHM Phantom QD that has dried up, cruddy Rocksett in the threads. Either I buy a 5/8-24 tap at @ $40 to clean those threads, or maybe someone here has a tap that would do this for me. I'd send you the FH in the mail with return postage and maybe a little something for your hassle. PM me if you're interested/ available to do this.
