the adjusting bolt has a grove in it,,, , when you install the bolt it can go in two ways one is the stock position reverse the bolt and the grove in the bolt fits into a arrow . the arrow is only on the front of one side and the rear of the other,,, you pry the bushing arm back or forward to move the arm to get the alignment
you see the grove is only there for most of the bolt



below you will see A & B is the car and 19c is the bolt and it can be moved back and forth if the bolt grove is not lined up then the arm will not move make sure the bolt is facing the right way because if in backwards, it will NEVER get the alignment correct. jim

just found another pic ,it shows stock on the left and adjustable on the right. set to the left ,turn bolt over set it to right.
