Ok, I bought a rebuilt carb 1970 7040240. This is a picture of the base gasket that was included. I email the seller and I say "Hey, you sent me the wrong gasket." The seller assures me they have 100's of these gaskets in use, but they will send me whatever gasket I ask for. I know it will work, but this is not Cuba. Right or wrong gasket? What do you guys think?
