While cruising some of the RX-7 sites I saw some picture of the 3rd
generation intake manifold.  I had never seen one before.  They do not have
the big high loop as on the earlier models.  they are flat over the top of
the engine, and look as if they are lower than the alternator and would bolt
onto the 2nd gen lower manifold.

Does anyone know any better?

Try taking a look at this site to see some pictures:

Yes I think you are right Dave. It does appear to be lower. I am not sure a 
new top will boltto an old bottom however.
