Been thinking about getting aero wipers but i just cannot justify the ludicrous price for GTI arms. In my searches i've found that a lot of people are putting GTI wipers on their Corrado's.. They are also putting TT arms on their Corrado's. If GTI arms fit Corrado's.. and TT arms fit Corrado's.. then surely TT arms will fit Lupo's no? Or am i missing something?
