K, Hopefully its like the 92' but here it goes. Over on the right side (driver side) look down and you will see the pulley farthest to the right there, look around and you'll find a slide type thingy. There are 3 bolts to lossen. Do so and the pulley will slide along the track inward, change it and when your tightening them back on, there is a pully on the left that has no real purpose, and just spins. Take that off and tighten everything as much as u can. Then replace that pully to add the extra tension.
