Sorry, I cannot answer your exact question in the form you ask with certainty; but, this will work...loosen the two nuts/bolts on each adjusting sleeve, mark the starting point, turn the adjusting sleeve one direction a few turns (count the turns) until you see it either shorten or lengthen then you will know which way to turn. Go back to the starting point and turn one turn each as necessary to shorten the right and lengthen the left.

It is common for the adjusting sleeves to be seized, put penetrating oil on them liberally everyday for 2-3 days...you will be happier!!!

Good luck!!!
