I've worked on my own Titleist adjustable clubs as well as hundreds of other OEMs with adaptors. Usually, I had an adaptor to work with from the previous shaft(s) but I have had to find Titleist adaptors on a few occasions. Lets just say it's easy but not THAT easy. Fellow clubmakers hold onto the few adaptors they have for future jobs so I've gone to eBay and had success. The thing is, over 95% of the adaptors for sale are non-OEM. They will work in most cases but may not be correct when it comes to adjustment specifications. I'm not an engineer so I can't break out my micrometer and say this type is good and this one is useless. So, you have to look at listings carefully and confirm the adaptor is indeed manufactured by Titleist. There are plenty out there and if money is no concern, you can get them quickly at $35-$50 each. I've bought the whole shaft if the price is right to get the adaptor. Lastly, I completely support Titleist NOT selling their Sure-fit adaptors separately. The time and effort they put into ensuring which shafts work well with their heads is extensive. Making their adaptors available without quality control (i.e. Their department installing them) would cause a long list of problems I won't get into here but many Team Titleist members know about. Best of luck with your winter tinkering and message me if you have any additional specific questions.
