I fitted Mk4 aero arms and blades and also fitted the polo rear wiper and blade.

I used to have the Bosch Aero conversion but never really liked the way they sat on the windscreen as the arm raised up at the ends
The new wipers sit a lot flatter and look much better!
Fitted the polo rear too
A quick pic of the part numbers needed for the windscreen wipers:
And a pic of the polo rear wiper part numbers:
Hope this helps a few members out
