I am trying to find replacement vacuum hose or tube for a 1979 Trans Am with air conditioning.

The vacuum hose that I am needing actually feels like hard plastic . The plastic brown vacuum hose or tube goes from the #2 position at the A/C heater control to the vacuum actuator that controls the cowl vent door (the door you can see if you look through the black pastic screen by the wipers) that brown vacuum hose connects also connects to a orange tube that should go to the passenger side vacuum actuator above the kick panel.

Anybody know where I can get these? Or can I just use normal rubber vacuum hose instead of the factory plastic vacuum tubes?
