Thank you for the information. Maybe I have the wrong heat shield. It has 3 bolt locations, to attach to the exhaust manifold, but there isn't any provision for any tubing. I was told the tubing attaches to the heat shield via a piece that clips on. ?? Not sure. I had a Fiat 124 Spider with the same type of setup, and the heat shield had a built in hose connection pipe, 2-3", on the manifold side. I can fab something together, as long as I can get through the visual part of the smog test. The emissions tests all passed.
