Yes, I believe that both the 32/32 and 32/36 2-barrel downdraft Webers use the same adapter kits.  (There is a one-plate adapter kit, and a 2-plate adapter kit)  FYI, I have Samurais with both the older 32/32 and the currently offered 32/36 Weber carbs, and I have not noticed anything different in their mounting bolt patterns.
I also think that most parts should be available for your older carb.  There are a wide array of older Japanese and European cars that had the 2-barrel Weber.  Even the Pinto and Mustang II used a Holley branded variation.
