Daily Update- What we know, what I think

After a bunch of back and forth, a bunch of measuring, and a bunch of scientific method, here's what we know.
1- The pressure plate rubbed against the bell housing.
2- We've measured all the things that could be too long- The engine-transmission spacer plate; the flywheel; the clutch pack; and the pressure plate. All are correct thickness.
3- In a reversal, we found out the throwout bearing didn't engage too much, but instead it disengaged too much, getting wedged against the bell housing. This left a lot of space and no pressure against the pressure plate.

SO, since nothing is too long / thick, I believe that the pressure plate only came in contact with the bell housing because the throwout bearing wasn't supplying pressure against it due to the arm that normally puts pressure against it wasn't because the slave cylinder was broken in two.

THEREFORE, now that we've replaced the slave cylinder, we should be able to put everything back together without any further problems (in the bell housing). However, to double check this, we'll monitor the clutch fluid for metal pieces from the bell housing.
