My friends neighbor has an early 60's CJ5, I think it's a willy's CJ5 actually. But he rebuilt the hurricane V6 and he was telling me it came with a 3spd and he wanted to find a 4spd that would bolt up as well as a transfer case that would center the rear diff becausew he swapped in scout axles. Any ideas? I think he said his orig. tranny was a T-90??? and his transfer case was a spicer 18.
