These are the same posts used in our Gearset Organizer Cases (Part No. 1402-20 and 1402-30). For those who wish to construct their own gearset case, these injection molded gear posts are available separately. They are specially manufactured to fit the Hewland / Webster Mk 8/9 gears (1.0" diameter layshaft). Includes mounting screw and high-visibility label to mark the gear ratio.
