Thought as much, i'm gonna crack on at it when i get up as i've just got in from work. I will make it work, big improvement on the scaffold which was there. Cheers for the help!
 
Sorted, it just needed alot more filing down off of it, to anyone who is thinking of doing the conversion, just do it, the results are great!.
 
I've just done this mod to my Ibiza and it was a piece of cake...took minutes to get the old style wiper off, sand the new wiper's cap down a couple of mm, and then fit the new arm and aero blade. Super easy! and a great result too. I can't understand why Seat don't fit these as standard!

I got the wiper arm off ebay for a tenner and can't wait for it to rain so I can test it for real :D
 
Brilliant - ordered off ebay and fitted this morning in 5 minutes. Ready for winter!
I bought ebay item no: 230880624396
 
Anyone know what the replacement Bosch blade is for this? I did the conversion but could do with a new blade and I want to double check before I purchase any Polo rear wiper from a similiar year!
