chatter. I just hope that if I do this job I can nail everything on the
first try. And thanks to comments like this and everones input I hope too!!

As for worn bushings: The Bently shows how to remove and install the
bushings but nothing on checking them. After the trans on the floor did
you just grab the release shaft(clutch fork) move up down check for play?
How do you accuratrly check for bad motor/trans mounts? The rubber is not
deterotatied but does seem to be soft and the motor can move easily?

I will be sure to check this and file those fingers smooth. Thank you for
