Another "what is this question"

Thanks to all! I was convinced and thought I remered after reading your responces that it was the air conditioning to manifold bracket. Life was good! Until I saw the post from Cavemanmoron. I really don't remember that bracket at the exhaust manifold. I will however give it a shot. The air isn't going back in, so...itt's the exhaust or a box in the basemant!

Thanks again,
Dave
