Ladies and gentlemen,
I am trying to locate a defroster duct for my '73 L-82. It is the upright duct which attaches to the heater/air box and runs upward to the grille on the dash pad. I understand it has been discontinued. Does anyone have a line on used parts. I have looked at numerous sites and sent out "feelers" to many loking for the part without much success. Any assistance would be appreciated. Thanks again, Hrvyhlas

Try one of the vette junkyards. Dutch at Just Corvettes is good to work with http://www.justcorvettes.com/ and should have what you are looking for.
