I picked up some extended radius arms (Duff or Cage arms) but it didn't come with the heim joints or frame brackets. I was looking online a found universal weld-on frame bracket and some johnny joints. The frame bracket and johnny joint both accept a 9/16" bolt. Googling around, I was able to find the directions for the Duff radius arms and they call for 1" bolt with their heim joint. Would I regret installing Johnny joints with a 9/16" grade 8 bolt? If so, what size Johnny Joint do I need? I know I could always order new parts from Duff but i've heard a lot of good things about the JJ, i thought I would give them a try,
