Re: Yes, they are still out there NUMBER 2
jGreat find, Bruce.
Looking over the engine picture, there is what appears to be a vacuum line running down over the drivers side cylinder head and also a bowden/push-pull cable running horizontally along the drivers side firewall. They both look like parts of a Columbia two-speed setup. The vacuum line would come off the top of the intake manifold behind the carb and down to the Columbia two-port valve mounted on the frame or on the steering box. The push-pull dashboard knob would pull the lever on the speedo gear changer mounted horizontally on the firewall about where that cable is living now.
Have you looked at the rear axle? Columbia under there?
