Jon,
The spring on the clutch fork should help take up the slack. Check out my post at link below. When you go through my post you can see where I used some nylon spacers (bought at Lowe's) to help with the "slop" in the linkage (picture with me using small screw driver as pointer). They are very durable but not sure how long they will hold up.

By the way did you put the SS springs you bought from me on your car?
