I bought a kit to change the throwout bearing in my transmission. I like the older bearing better than the new one. I have changed a few of these, but this is the first time I needed to change the kicker clutch. The new clutch is smaller and designed to fit snuggly inside the bearing. The newer style is on the right and the upgrade to the older one with the kicker clutch is on the left. Also changed the pushrod as they are different.
