5. If the recorded value of frictional torque is reached before the 30mm bolt has been torqued to 180 nm then replace the elastic spacing sleeve.
So, if this is correct why would anyone start this project without a new spacing sleeve? Which one of the dozen listed for a 1985 380 SE differential is the correct application for my 1985 380 SE? How do I find out which one is right?
Do I have any of this right?

The crush sleeve or "elastic spacing sleeve" is between the two tapered roller bearings on the pinion shaft.
To get to it you need to dismantle the entire differential.
The other problem that can happen when trying to get back to the same friction is =>
The whole measuring friction thing is trying to set pre-load on the tapered roller bearings - this can go wrong big time when the bearings are worn. You just won't get near to the friction you measured when you took it to bits. Also in the FSM there's a minimum friction that should be there in the first place - if this is not achievable then the bearings need to be replaced.
If the bearings need to be replace you need to go through s tricky process of adjusting the mesh of the pinion and crown wheel to stop whining / weird noises / over heating / death and destruction...
...as for your last question do you want to know which final drive ratio was fitted to a particular model?
