Here's a couple pics. I'm sure you'll notice it has an incorrect exhaust manifold on it in these pics. When I bought the truck the drivers side manifold was cracked, so I swapped it out for one I had laying around the garage.
I just remembered that after I had the exhaust tin blasted at the time of restoration, the inner tin portion (the piece between the manifold and head that the outer tin fastens to) appeared to plated. It came back from blast with a silver, cad plating look to it. Almost looked like aluminum, or galvanized. I tried to find a pic of it with no luck.

Well there you go. Great pics. Thanks for sharing.
...btw, the site is on fire. Feel like I've learned a lot this week.
