Air filter

[stoffe2000]

I am going to put an solex 34 in my HY78 from 1970, an former owner of the van used a weber instead, worked no good...

So, i´m putting the original stuff in, but now i need an advise. What is the air filter supposed to look like?

Take a look at this picture:

I´ve found pictures of different kinds of air filters, but which one is the right one for my car...?
