We would measure the butt diameter of the shafts with a pair of calipers. If it is a .600" butt diameter shaft it would use the S60 (.600") steel shaft extension. If you can tell me the manufacture, make and shaft flex of the shafts you have there is a good chance I can tell you which size extension you need.
