Vent cables and knobs

[56hotrodred]

I want to keep my fresh air vents and want to get the cables and knobs and operate them from the two upper outside stock holes in the dash-the choke and throttle holes I think!

For those of you who have done this what cables did you use and where did you get them and the knobs. Are the knobs interchangeable as I would want them all to match on the dash.

Thanks in advance for any help.
