Well, I got the spare, youthful gearbox apart. The 5th gear set is off, and the input & output shafts are free.

Took longer than I thought it would, but these things always do the first time. I probably missed some crucial step that would have simplified things, something like leaving it in neutral or some other gear to enable things to slide apart easier. Also, I don't have c-clip pliers and could have used them.

On the plus side, I learned a few things about transmissions today.

So tomorrow morning I'll pile the loot in a box and head back up to the machinist. I'll report back on what he thinks.

FYI: having gotten this far, I don't think a straight-up 5th gear swap would qualify as a "very easy" job - it would be even harder doing it in the car. Of course that's subjective depending on your skill, experience and tools/facilities (mine being: average, zero when it comes to transmissions, and average).

ZeroFuel - could you let me know what you'd consider to be a good price for a taller 5th gear set? (PM is fine if you don't want to post publicly.) It could help in my conversation with my machinist if he's interested in producing multiple sets.
