I know folks have "discussed" those alternate parts before but unless your good doing metal work and want to drill new holes in your window frame they really are not an option. I got hold of an old VW latch just like in that post above and could not figure out how it would work the same. You'll need a different striker plate, hardware, and need new holes to mount it with. On top of that it just does not work like the ones we have now with how the current bracket mounts to the window frame.
