The picture doesn't help very much. Can you take one back a little bit more to see things better and maybe the whole manifold? The 1.7 did come with a carburetor but it was a single barrel and an adapter would be required to mount a 32/36. There are other VW carburetor manifolds which would work also but they too would require an adapter. Most "kits" sold for VW engines include an adapter which often bolts to the rubber/metal carburetor mounting gasket. These ruber/metal mounting gaskets are expensive and often hard to find now. But try a different picture and maybe something will show up.
