Not mentioned below: the engine air-filter box bought on eBay arrived with surface rust but in otherwise good and unmolested shape. It's a 1971 part but they are hard to find, so it will have to do for a 1972 car. It needs only sandblasting and paint: the same factory spec semi-gloss silver as the valve/rocker cover.
