The 1/8-inch plates easily conform to the curvature of the control arm with clamping. Now is also a good time to see if the torsion-bar- adjuster pivot at the end of the arm (arrows) has too much side-to-side clearance. Pulling in the sides of the control arm for a flush fit while clamping the plate can reduce the clearance. The anchor does not move relative to the control arm once the ride height is set, so little to no clearance is required. The fit of our plates is right on the money.
