The 20mm Vector E-Track Mounting Ball mounts directly to the JL E-Dock and will work with 67 design standard arm ends. So don't forget to pick up some 20mm balls and add in a couple of 67 mounting packs from us before you check out. 1/4-20 thread. This product does not work with the 2007-2010 JK E-Dock, 2011-2018 JKE-Dock, or the JL/Gladiator Full-width Tube dock.
