This is a very nice used air conditioning, heater, ductwork, lower under Dash that we removed from a 1977 Chevrolet El Camino with a C. This is in great condition. All mounting tabs are nice. I see no issues with this at all. Please see the picture they are of the part you will receive. We do not use stock photos, we take actual pictures of the parts. Not sure on this but it should fit 73 through 77. El Camino and GMC spread. Again, this was removed from a 1977 El Camino. Please look at the pictures and make sure this is the part you will need for your application. Thanks for looking!
