This is just a heads up for folks that are going through a shaft fitting for a TM R9. Apparently TM has changed the design for the interface at the base of the shaft. It is longer now extending up farther into the shaft. If you have a new R9 your shop may only have inventory on the older interface and will need to get the new one in to make your shaft change. They may not have seen the interface on your club. You might want to highlight this for them so that they make sure they already have the parts they need for you or at least know to get them.
