V8 center link for 64 Dart GT

Hey guys and gals, I am looking for a dropped center link for my /6 to v8 conversion. I remember a while back somebody posted about a company that was making these again, and I remember checking them out and the price then was 250.00 I think. Does anybody remember that? Also I am looking for a decent running v8, not particular about size, just a small block. I don't need all sorts of power for a 2800 lb car. I am in southeastern Ma. but could possibly travel for the right deal.
