Ed,
I don't have A/C or center console. I see #11 in the aim, but don't see where it attaches to the fire wall. If your looking at the fire wall from the front of the car, the hole is on the left of the accelerator pedal. The duct would have to go past the accelerator to attach to the hole in the fire wall. After 50 years it's hard to tell what somebody drilled holes for. There are 2 holes, one drilled a 1/8 of a inch above the other for the carpet guard around the steering column, who know why.
