Great find. This manual is just what I needed as the owner said the synchros in top gear are a bit notchy and jar your wrist as you turn the input shaft. Should be worth spending $500 on an overhaul.
That is it. Just looks like the rear support changes to meet the application.
PS Just looked at the prices on your post - lucky to do a full rebuild for $1,000. Still worth it as it will protect the cook's wrist as she spins the shaft so I can practice racing changes while making Ferrari noises.
