I agree with the rear RockerArm 'orientation'... unfortunately I think it may require the entire assembly to shift forward of chassis. Separating BodyPost mount from RockerArm if you want to keep bodyposts where they are. (New TopDeck)
Not to say that you cant get this configuration to work.. will just need to play with spring/oils. But you will also have more room to 'preload' the coils if you move the assembly forward to 'correct' the Rocker/PushRod angles.
