Hi All Noticed recently on my 2014 Insignia, a piece of trim had gone missing, I have no idea if it was stolen or just fell off. I have ordered and received a replacement part and just wondered if anyone can give advice on the best way to fix it, do you just push the clips in and hope for the best or is there a specific way to do this? I have tried but just couldn't get it to clip in. Thanks In Advance Jason see attached pics

Hi All Have owned the car for 5 years now and basically its been trouble free, great for long journeys and very economical. Jason
