i just got hold of some silver estate roof rails for my black xp. great buy i wont say how much
i got home and aaaahhhhhh!!!

ive see on my estate the painted black plastic trim goes from the bottom of the windscreen all the way to the back of the car.
i have done some searches and i believe i have to cut(trim)this at where the roof bars meet the top of the screen.

is this the case, and does the existing trim with gutter clips just pop out or do they un bolt from under the curtain airbags like the roof bars. does the existing trim come away from down the windscreen or is it just glued on.

sorry for the questions but don't want to **** it up.

thanks in advance nigel
