After recently replacing the clutch in my 89, we found where the tob had worn quite a groove on the shaft. Over the past year, I was experiencing random shifting problems and rattling from the tob. After getting everything reassembled, I am completely amazed at the difference in driving characteristics of my car. The clutch pedal feels perfect and no longer catches on the groove. Shifting is so much easier! Being a tightwad, I tried to stretch out this repair till it was physically required. In hindsight, I should have replaced the clutch/tob when I first started experiencing problems. What a difference!
