Spitfire Manifold for Weber carb?

[Jeremy DuBois <jer@thlogic.com>]

  At my family reunion this weekend in Utah, my uncle mentioned that he had
a Weber Downdraft carb that he had taken out of a Datsun 240Z years ago, and
is just sitting in an old box, so he's going to ship it out to me in case I
can put it in my 76 Spit.
  Now, the question is, where do I get a manifold, or manifold adapter for
the weber? Anybody have one to sell?  The other problem is that I will need
a different jet than the one that's in there now, but that seems like a
lesser problem.
