Know this post is old, but I purchased a set of these reproduction manifolds probably five years ago from YearOne, they were concourse reproductions however, the drivers side had a casting flaw that someone tried to fill with some kind of putty or filler. I contacted YearOne and they didn't have anymore in stock so I sent them back and bought a set of Doug's Headers. Anyway, I would still like to have a set of these repops but I don't believe anyone has them anymore.
