The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Muncie 3 and 4 speed part not available ....Where to source?

The repair of my '64 C10 3 speed tail shaft has gotten harder. Now I'm replacing bearings in the tranny.
After complete disassembly we found no 'energizing springs' in the tranny. They need to be there for the synchronize to work correctly. They are unavaible from my tranny source "Anaheim Gear". Anyone know where I can source them? Thanks.
