You can get a shaft from anyone that builds shafts. Was it a 5/16-14 pin?
If you're trying to match the ringwork your list is a little shorter- pictures would help.
PM'd you about the super Nova shaft I have. Let me know. Just confirmed the brass pilot ones were done early on before the phenolic, that some some folks are saying had a problem. Just got off the phone with one of the former owner/investors that confirmed these are original Nova shafts. One, and only one, available. http://forums.azbilliards.com/showthread.php?t=310300
