Ages ago some time last year when I bought my anti roll bar bushes from Milner off road I thought I might as well get some wiper blades as they where cheap, well Ive fitted then just now and they are to big

just, they will work ok but for the MOT I think I will fit the old ones back on, the new wipers sweep over my FOG windscreen sticker, so theoretically it could fail the MOT.
The Milner wipers are 21" so 20" would be fine
