very slowly undo the screws HAHA
but you are still very likely to get some broken fixings. when you do get it off I really advise this little mod I did on mine. I used a tube of sikaflex 227 and an old toothbrush. Firstly glued all the fixings back on with the sikaflex, then using the tooth brush I smeared a thin layer of sikaflex over the entire inside of the trims. Then hit the outside with plastidip.
I had them sitting on a perch drying and the wind came and blew them all off and they hit the concrete. I know I was freaking out about them being smashed but they were just fine, no broken corners. I think I have successfully made them nice and strong again, resistant to cracking at the very least.
