I'm restoring a '62-'64 Corvette cast iron intake manifold part number 3799349 for 300hp 327's. The sheet metal oil splash shield on the underside is severly rusted through and needs to be replaced. A good one looks like the one below, held on with four rivets. I can't find any part number for this shield - does anybody know this number or better yet, have one lying around? Was this shield used on other manifolds?
