Per every reference picture I have ever seen and Osborn pages, I mounted the Air vent knob bracket to be immediately left of the steering column as pictured.
When I go to attach the baffle arm to the cable, the cable length appears more than 2" longer than it 'should be', I have to bend it far to one side to connect and clamp-it does not operate smoothly.
It almost seems it wants to be mounted closer to the door pillar. The second picture shows 2 ready holes under the same dash edge. It looks as if it may have been mounted here before (or something was). From Osborn manuals that looks like where a 6 cyl choke control cable would mount. And if I do mount the Air knob there it looks as if your left hand would get knuckles skinned when you go for the parking brake.
Please set me straight here.
