Stewart Warner Tach Mounting

[brianc427]

Does anyone know how the Tachometer is to be properly mounted for a Stewart Warner 970 Tach for a 69 Yenko Chevelle? I am pretty sure it goes overtop the steering column, but I am at a loss from there. I have the pedestal, and I am not sure if you just use that or is there another piece I am missing? Do I drill holes in the dash and use those holes in the pedestal? Any pictures of an examples would be greatly appreciated. Thanks in advance to everyone.
