High torque starter to fit a air cooled VW transmission. To determine an exact application would need Cargill measurements and check the rotation.

This is a generic gear reduction starter that's been machined to accept an adapter plate. These starters are used on lots of different vehicles from small 4 cylinder engines to big V8's. This one appears to be made to fit an air cooled VW but without exact measurements it's impossible to be 100% sure but VW's do use a 9 tooth drive gear. There are many manufacturers of these gear reduction starters (American & Chinese) and many companies are modifying them for specific applications. The URL's show a few that are available for VW's. Please note, not all the starters look exactly the same (different manufacturers) but the adapter plate almost always does. The extra holes are so the starter can be "clocked" or turned to the desired position. Some adapters have 3 or 4 holes, some only 1 or 2 holes. It all depends on the maker. The last URL has a photo of one that looks closest to yours. It was available from Go Westy VW Parts over 12 years ago.

Reason:
thank you for the opinion, I see what you are saying, but the only thing that confuses me is that the starter I have does not have a plug near the battery terminal, all the ones you reference have a plug there, are those interchangeable?
