Since I got goofy with the lower arms I decided to make some tube uppers. Again I used screw in ball joint sleeves that were left over from when I was racing modified circle track. Just so happens the stock a body upper ball joint screwed rite in so it was game on. I used my old arms to make a jig with some flat plate and hold everything in alainment when welding. Heim joints are 5/8 left hand thread and the clevis stud are right hand. The stud was just a grade 8 bolt I cut the head off. I made aluminium spacers to keep the hems from binding and allow them to work with the 1/2 eccentric bolts. This also gave me more adjustment range with tubes and eccentrics. I did have to move the rubber bump stops over and redrill the holes to line up with the tube.
