My first thought would be to replace them with the rod ends from the z1 arms which are actually pretty nice. Unfortunately the z1 rod ends appear to be rh thread and the gk-tech need a lh thread. So where I am is I will need a lh thread 3/4 16 rod end with a non metallic cylinder bushing. There seem to be a few off the shelf options available at speedway motors and summit racing but I am open to other sources and input from anyone with fabrication experience.
