Brian, it's basically a cleanup of an old Dart design. The aluminum cable pull plate is a water jet cut piece, edges smoothed with the belt sander, 5/64" cable holes cleaned up on the drill press, center hole tapped 1/4-28 and the seats for the ball cable ends drilled into the face 1/8" deep with a 17/64" drill bit. I have a DXF file for anyone who wants to duplicate the setup, and who doesn't want to bother making one from 1/4" aluminum strap. Threading the throttle rod is the hardest part. The rod guide and the holder for the cable housing compression fittings has to be designed to fit your particular kart, and the fitting hole spacing is the same as the cable hole spacing on the aluminum pull plate. The compression fitting holes also must be tapped 1/8-27 NPT female thread from the fitting holder face that's toward the back of the kart. TJ
