I am the original poster and have no idea what you are talking about. Not sure what happened here with this thread. I was just posting a pic of a cool bike and asking for some insight to what motor it is.
Those arms are most likely Burgard or Magnum, same thing. The ball joints are probably Moog automotive style tie rood joints. I can't remember the part number but someone here will chime in.
Good god! Finally, someone made these to fit aftermarket arms! Nice looking product! I hope to get these for my a arms. JD might consider making a recessed dimple for the mounting bolts to prevent them from being sheared off.
