Just search on Ebay or google for it, and you will find several new ones for
around US$150.
If you can get a later (1977- ) inlet manifold for the 95/96, you can also
use the two stage Weber 32/36 DGV series (DGEV or DGAV) or the Solex 32 TDID
(as was used standard on the '77+  95 and 96 in the European market) . You
will have to adapt the air filter housing as there is not enough space under
the engine cover. In all cases you will also have to have the carb rejetted
for your 1700 cc engine. The Solex will work as is, but was used on the 1500
version.

Motorsport Service probably has them, and possibly other options you
haven't considered. They're in New England somewhere, I have the
contact info at home if you can't find them.  Jack Ashcroft might be
another source.

What's your project, Mike?  Sounds like fun.
