Thanks mate. I thought things were worse than they were. On first look the trim/guttering looked to have torn rubber on the underside. I thought it had torn a lower part of it. Turns out it was just sealant from a previous life. So all good now. Original guttering will be reusable and ive found a pile of clips on fleabay!
Have a look here :
Looks like the trims are no longer available but you can still buy the clips
