Hard shifting issue resolved:
.
- Apparently the new aluminum bellhousing is a bit meatier than the cast iron. The clutch slave cylinder mounts in it's holder easy enough but the aluminum bell spaces it outward thereby causing the slave to not fully disengage the pressure plate.
- There are two easy fixes to deal with this.
The first is to simply slide something over the end of the clutch rod so it's effectively lengthened and then the thicker bell is addressed:

- The other idea takes a bit more effort, so it is the likely winner. Remove about 3/8 inch of material from the body of the slave cylinder to it will push into it's holder further and engage the clutch rod early during the stroke as it should. The red area is where the material was ground off:

It now shifts with effortlessly and the pedal grabs partway through the stroke - not 1mm off the floor and not 2mm from when your foot releases the pedal.
.
Time to look at the overdrive problem...... Again.....
