Does anyone have any tips for re-fitting the B pillar trim, particularly drivers side. The kn@bs who did my plyling and carpeting ( among the many things they've made a mess of) have left the top of the trim sticking out. I can see a clip/stud that should be holding it in place but can't figure out how to get it back in. Do I need to remove the trim and start again? If so, start the top? or bottom? Any help please.
