This photo shows the lower trailing arm after the lower coil perch was removed and replaced with a reinforcement welded beween the two side of the arm. Identical ti the reinforcement that exists on the opposite side and end of the arm.
Cut off existing bracket and welded on the extra steel on the left to bolt a modified Ford Racing clutch quadrant to the arm. Much better and smoother operation.
Witness mark obtained with 90* at Mid Lift at both ends of Miller Rocker arm. Unable to get anything this good Location included with other rocker arms.
