My company seeks cast aluminum intake PLENUMs (only). This is the section circled in red. Please DO NOT ASK FOR DRAWINGS. We do not wish to manufacture a new part. This product already exists and is available in China. We want you to FIND this part for us. Again, DO NOT ASK FOR DRAWINGS. Only show us what you can already supply. We will choose what we want from what you can supply. If you do not have supply of plenums, then DO NOT contact us.Thank you,P.S. Anybody who asks for drawings or specifications will NOT get a reply.
