Aside from the fact that the T56 weighs on the order of 120-lbs and will be a bitch to wrestle around without the car on a hoist and without a proper trans jack to take the weight, doing a clutch isn't rocket science.
Just get the details right:
- re-surface the flywheel (make sure the dowels are re-installed afterward)
- use red Loctite on the flywheel bolts and driveshaft bolts
- replace the pilot- and release-bearings
- inspect, de-burr (or replace if needed) and lube up the input shaft collar where the release bearing rides
- remove any anti-corrosion coating from the pressure plate and keep oil off the disc and flywheel surfaces
- lube up the release arm fulcrum
- tighten the pressure plate evenly and in a pattern to final torque
- put a bit of trans fluid on the trans output shaft yoke when re-installing it
and you won't have any problems.
