I would try chevs of the 40's. Of course my experience is about 15 years outa date but they were great to deal with then and they are still around so that has to say something. I was building pre internet days when it was a hunt to get the parts you needed wanted and ebay has blown me away with some of the things I have seen over the last moth of browsing. A bit of redundency but still looks like a great place to get what you need.
