What are you problems are you having installing them. It is a pretty strait foward installation. The only thing I found out of the ordinary is I went and bought some nylon bushings to keep the quadrant from moving left to right on the shaft. The firewall adjuster replaces the rubber piece in the firewall on the exterior side in the engine compartment. You will need to take off the stock rubber one and replace it with the adjustable one. It will screw in using one of the screws. The quadrant is held on by a couple of clips pull them off and then work the quadrant off and also the smaller plastic piece behind the quadrant with the teeth. Slip on the bushings and then the quadrant and then the next bushing put the retainer clip on again and adjust the the clutch as neccesary. It may sound a little confusing now but once you dig into it it will make sense
