We would use any .355 ferrule with an OD of .535″ and turn it down. Depends on what length you want. Probably a 89TI, 91TI, 93TI. Not sure Ping used a ferrule on that model in 2006 even though it had a straight top. The S59 did not. I don’t have the S58 on site to measure the top of the hosel (Ralph has it), but the S59 and all similar models I could measure were all right around .530″ at the top of the hosel.

Thanks Britt. Yes, my S58’s have ferrules. The hosel OD varies but max is ~.530.
Do you know or can you measure the outside diameter of hosel?
