Parting out My 65 Barracuda

Under the drivers side dash is the fresh air intake from the cowl. It should be round, approx 15" high and have a metal door that opens and closes to allow cool air in and keep it out in the winter. It is bolted on buy a long rod that is threaded, so pretty easy to get off. Is it still there, is the door there, and does the door open/close or are the little metal hinges rusted out as mine did? If its still there do you want to sell it?
Thanks,
Doug
