Frank - I think for all intended purposes that your topic really belongs in the
Driveline forum as it's not really engine related, so it's been moved to the correct forum for further discussion and help.
As to your question about replacing the existing throwout (TO) bearing, I'd suggest you disconnect and raise/brace your torque tube and pull the transmission back as suggested by klhansen above. You should have it fully supported, secured to a transmission jack or suspended using a hoist to prevent accidentally dropping it on yourself when trying to pull out the TO bearing. Safety First!
