I'm having the same issue as the original poster. But have been unable to do it after sleeping on the problem. I wouldn't part with my Disco 2, and would hate to have to replace it. But, I just cannot properly re-fit these A-pillar trims.
The video doesn't show whether there is any gap at the front between the windscreen and the trim. The man also throws away the old spring clips.
Can someone tell me please whether the spring clips are no good after they have come off, and so should be replaced? I'm also wondering whether my actual trim is deformed, as when 'fitted', I have in places a 1cm gap between trim rubber and windscreen.
Also, is there a knack to putting this back on? Did those who have succeeded here do it as shown in the video with the plastic rivets first then the spring clips bashed in with a mallet? I found that by doing it this way, there was no way that the spring clips would engage. The only way that I could get the spring clips to fix was to put the bottom spring clip in first then work my way up, but well I've not got it back on properly, so maybe I'm going about this wrong.
Any help is appreciated.
