I got the opportunity to upgrade my 5th gear set to a "taller" ratio (.642 vs. the stock .704).
At the point where my ZF is now, the a 5th gear update to the input shaft needs nothing - I am just waiting for the new gear set to arrive to complete the assembly.
The output shaft is a slightly different story. The 5th gear is the last gear on the assembly (right up against the roller bearing before the pinion), and the entire output shaft assembly has to be disassembled. Luckily, this was a pretty straightforward process. This was accomplished today - to get ready for reassembly.
In this disassembly, we had not done anything to the output shaft, as my second gear synchros, etc. are all on the input shaft. Once the output shaft was disassembled and cleaned, we evaluated it as having a clean bill of health!
One thing left - Lloyd at RBT says the "taller" 5th gear needs some clearancing of the 4th/5th gear shifter shaft. I will find out more details when I talk with him tomorrow.

The speedo drive gear did not want to come out very easily. We also marked this - obviously it has to go on in the correct orientation.
