Ive carbon wrapped my roof and the standard aerial makes it look rather poo tbqf, and I have gone and bought a shark fin, what is the best way to go about changing this with out doing any damage to the roof lining and roof it self? going to be doing it tomorrow weather permitting so quick responses would be muchly appreciated,

Pull the back off the roof lining down and there's a bolt. I found it kinda annoying to undo.

so I wont need to take any thing off i.e panel cards or anything?

The back pillars will need to come off. It's only like 3 screws
