Mike - where's the adventure in that? :)
After getting inside the tranny and seeing how beefy the mod1 pinion/spurs are for the two-speed, and the steel drive gears, I'm pretty sure this one will hold up forever. Now I'm just considering dropping the manual brake.
Since I installed the FOC it's so much lighter that I'm very pleased with it.

Starscream - drilling through the shaft and using a pin was one of the ideas in my post. It's probably what I'll end up trying first. The one-way functionality isn't really required for the two-speed to work, only it's physical presence since the second gear spur bearing fits over top of the one-way.

If that fails, I can just jb weld everything together :)
