UPDATE: The older Grip assembly (3 part) uses Grip2insert. The newer one uses Gip5insert.
Nest a 10-32 hex nut into the slot in the bottom then screw slide the
...Plus 8-inch threaded rod through FrontButt, the 6-inch spacer, then screw it into the nested hex nut until there's JUST ENOUGH threaded rod remaining to get another hex nut onto the exposed end of it.
