Mike, I don't have that type of air cleaner and I check 2 different versions of the parts manuals and both of them show an air cleaner that is like mine. A non-oil bath filter version.
Is it possible that your engine was retrofitted with an old style oil bath air filter? Or is it possible that I have no clue what the heck I am talking about? My experience with oil bath air cleaners is with antique Oliver tractors and the little filter on the VW engine is nothing like any of the old air filters I've seen on old tractors.
I guess in any event, I would opt for a paper or screen element air filter over an old oil bath type any day. If mine had an oil bath system, I would convert it to a low profile standard air filter. (It needs to be low profile to fit under the hood). There are literally hundreds of sources for VW engine components, you should have no problems finding one that will easily fit.
Below is a copy of part of the parts manual, it shows the type of filter that I have, and that I have seen. Part number FL7118/1 is the air filter.
