I had a real time with mine a while back, but finally got it right. I don't see how you have no free play. From what you are saying, it seems that the adjustable stop post may be too close. Maybe your arm stop post needs to be taken off and moved back one link toward the rear of the car to allow some more room for movement & adjustment. If your adjustable bolt on the slave is near the eye, there should be some free play there to start with. Have you checked Mike's site below?
