On that advice... I quickly hurried to retrieve my thrown away bosh wipers lol ... I managed to wrangle the clip of both of them and switch them on to the wilkinson wipers, the fit perfectly and the wipers are now sitting firmly on.
To add these wipers clear the screen better than the bosch ones! .. how long they will last is unkown but even if I have to replace them again in 6 months its still works out cheaper than the bosch ones. I guess sometimes spending more isn;t always best.
I did not know I could get so excited about how clear it wipes my screen lol. Time for me to get a life lol.
