Not to take anything away from your issue Jonesy, but God I love my Defender. I can open all the windows, even the two back ones, (crew cab) and feel the wind in my hair [bigwhistle] (yeh I know,,, what hair).
It just looks natural in a Defer ;)
Glad its all sorted now.
Ah, but Chops... you don't really need to open windows as there are already so many gaps in the Deefer - it is already "hair" conditioned! :D
