Bongo Fury

I`ve just recieved a pair of Climair wind deflectors from Bongo headquarters and tried to fit one of them. Now maybe I`m being a bit thick, but I can`t seem to get it to go on and I don`t want to break them
Has anybody got any expierence with fitting these, and or any tips. Cheers Ian.

O.K. The thicko here has solved it I was trying to get them between the door and the window rubber , anyway their on now and look great. Cheers Ian.
