I have an old Spalding TPM 18 Tour Series putter that I would like to extend by about 1 1/4″. Do you carry a shaft that would work? The present shaft has a Spalding label with True Temper on it. It looks to me like it might be an over the post shaft rather than one that inserts into the hosel? If you don’t carry a shaft that fits, which size shaft extender would work?
