The lid Jim just gave the link to is a correct stock lid for a single 4bbl. air cleaner. They all came painted black on a Skylark GS. The one in the link must have come off a 63 Riveria since it is red. The Buick accessory chrome dress up kit came with a chrome air cleaner housing, but it still used the black painted lid. If you want a chrome lid, you are going to have to get one chromed. The 2-4's lid is chrome, but it won't fit on the single 4bbl air cleaner.
