I am looking for a air inlet valve for a 1970 cutlass with factory air it was broken in an old accident. looked on e bay was unable to find one.

 

Need some more details......what is a air inlet valve?? Post a pic of the broken part.

 

Its the door and duct in the passenger side kick panel area that lets outside air into the car. The owner wants me to look into a whole new vintage air system now, the price of the broken parts are starting to add up. The case in the engine compartment is also broken and the firewall area that it bolts to is damaged and not flat it will need to be fixed so a new case would seal properly. The vintage air system would solve these problems. I like to keep the original stuff myself but its not my car.
