1966 Barracuda Fan Shroud!
I was concerned about mine overheating also. It really never got about 200* though.
I found one on Craigslist using the nationwide Craigslist search engine:

You also want to make sure you have the front rubber hood to radiator seal. It helps keep air flowing through the radiator.
Here's a picture of mine. Looks just like 66 Cuda's!!
By the way, since this picture, I replaced that hideous looking flex hose!!
