I have read that the top corners and the piece between them have been reproduced by a company in Michigan. Have not heard about a reproduction of the two lower corners. I bought all these pieces back in from GM years ago, wish GM still carried them.

I think the company Jim is referring to is "Caledonia Classic Cars" in Belding Michigan (616-794-5026). They reproduce a lot of birdcage and frame components. I have an old catalog, but the diagram showing their reproduced birdcage parts is confusing.

The color of the birdcage is not visible unless some of the interior trim is removed, but if you want the color to be authentic, it should be a green zinc chromate. It looks like the primer found on aircraft aluminum, and it comes in two shades of green on Corvette birdcages. I don't know which is correct for 68. Check with Quanta Products (800-235-8788); they can tell you what you need.

From a practical standpoint, the zinc chromate is fine for duplicating the color, but I believe I would apply a quality epoxy primer like PPG's DP-90, to the bare, repaired metal, and topcoat it with the green zinc chromate within 24 hours. In my opinion, the zinc chromate did not help much in preventing the corrosion in the first place, but then in that environment, galvanizing might not have been successful at preventing the rust.
