The wiper system is classic Mini, like this but I got and old used set for £15.
The wiper arms and 8" blades I got from CBS as they are fully adjustible arms and I didnt know how long I would need to make them once the wheel boxes were installed. Now I know the length I could probably cut down the standard mini wiper arm I have but meh.
All in ~£70 for the wipers.
Cheers
