84 K5. Centerforce 11 clutch. 9 months old, approx. 7k. Cold driving, shifts easy. Stop and go traffic, heavy traffic, shifting into gear is hard. At times it grinds just before shifting, not always. The 1984 owners manual says that freeplay is to be about one inch. The adjusting bolt and nut are almost to the end of the bolt. I have about less than 1/2 an inch before no more threads. If I adjust the bolt and leave over an inch or so of thread, too much freeplay. RPM's are 700-800. Suggestions? I did change the fluid and it's full.
