Your 2.0l air cooled is a Type IV VW/Porshe Industrial Engine.  Same thing used in the Porshe 914 and the ever popular VW 411 and 412.  Bus Boys used to list a sandwich type adapter in their catalog.  You probably want to be sure that whatever cooler you install has some sort of thermostatic control.

Anyone know of a place to buy the sandwich adapter that goes between the
oil filter and the block? Maybe there is no such thing? <shrug>

BTW, can someone tell me what Type* engine the 2.0l air cooled is?
(Type2, Type3, etc)

Thanks a lot,
