the upper arm is split with a clevis.
All the camber caster is adjusted off the top arm.
Again brackets are removable and bolts pass in the vertical direction.
The reason for this was mainly to keep the joints in compression and contraction when loaded.
The front upper joint is in a fitting that has an outer L/H thread and a 1/2" inner R/H thread.
By rotating the threaded sleeve (the part the rose joint is screwed into) I can adjust without removing the bolt out of the upper inner joint.
