Exhaust manifold heat shield

[ODFever]

I recently installed a muffler heat shield I bought from Mike's. It definitely reduces the heat radiating from the muffler, which makes my wife much happier. My wife told me that her feet were still getting hot though. After looking under the hood, I discovered that heat she feels is coming from the exhaust manifold and vertical muffler pipe. I want to build a heat shield for the vertical portion of the exhaust manifold and the muffler pipe since that's the source of the heat entering the cabin. I can attach a piece of galvanized steel to the manifold and the pipe. I'm not sure how to bend it around the muffler clamp and still have room to clear the throttle armature and the GAV rod. The steel also needs to fit between the rear engine brace/mount and the pipe. Do y'all have any ideas as to how I could build a heat shield like this?

Thanks!
