Hey Jeff,
All you need to do is hold the stop with a wrench and loosen the lock nut that is on the left in the picture that is against the steering knuckle. After the lock nut is loose turn the end of the stop that is on the right side in the picture to the desired adjustment. You might want to look at the stops to make sure that there isn't any excessive wear on the ends of them. also check that you don't have any abnormal wear in the pockets where the adjustment stops hit the pockets on the lower control arms. If you need any help you know my #. Good luck, Eric
