Post #23 in your previous thread suggested you check the runout of the flywheel with a dial indicator while it was bolted to the crank, BEFORE BEFORE BEFORE BEFORE, you took it off.
Did you do that???? Did you do that????

If you did that and it showed to be less than plus or minus .001, you can re-use that flywheel by surfacing it lightly.

If you did not do that, you need to start at the beginning and dial the crank flange.
If it is good, proceed.
If it runs out more than .001, the engine needs to be torn down and the crank flange trued.

If the crank flange is ok and the flywheel is ok, the pressure plate was the culprit.
After you either have the flywheel surfaced or get a different flywheel and have it bolted on, CHECK THE RUNOUT on the clutch surface area.

Your problem was caused by something running out as shown by the wear pattern.

Have the new flywheel and clutch balanced. Have the flywheel balanced ALONE, then bolt the clutch on and balance the whole assembly. Be sure they index mark the clutch cover AND flywheel when done.
Make sure they understand to balance the cover by drilling the SPRING STANDS and NO drilling on the cover itself. Absolutely NO WELDING weight on.

If you follow this and Mac did his job, your clutch won't chatter or slip.
