The B-trucks use a 32/36 DGEV (I have that, six years now).
Redlineweber.com lists a DGEV carburetor for the air-cooled VWs. Here's what there web page says (the E is for electric choke):
"The DFV Series offers the same increased performance, economy, drivability and excellent values does the DGV Series. The basic design of the DFV carbs is that of the DGV Series. but as a mirror image, with the primary and secondary barrel position reversed in the body While the throttle lever in the DFV rotates in a clockwise motion it rotates counter clockwise in the DGV. The DFV also features a power valve circuit to facilitate low vacuum running conditions-perfect for long duration, high output situations. You get the same value, parts availability and durability as with the DGV in a carburetor suited for your needs."
My VW is 1835cc and I run a single Weber 40DCNF, many years now.
