So last weekend I went to a swap meet in San Antonio and picked up a DANA 3 speed planetary gear gizmo. I'll play with it, but not sure if I'll keep it or not. It's missing the original off side crank, but I think I can find some cottered cranks to fit it. If I were to keep it I'd definitely go the route of adapting a stick-shift to it, and probably put it on a 20 inch stingray lowrider - they are impossible to ride anyway so why not complicate it more? lol I'm guessing they are not the most efficient way to pedal a bike... but it's a cool piece of 70s history and definitely a hot rod component of sorts.
