There are 3 clips that hold these in. You can get them from Rovers North. Part number MUC3186. The clips slot into the plastic structure of the a pillar trim. They slot in from the top. I’ve included a picture of the slots from an ebay listing. It looks as if you can slide the trim down and out of the clips but the dash snd body are in the way and seem to make this impossible. I used a forked trim tool to pry on the clips. This broke the clips. Try to avoid breaking the platic slots on the A pillars. You can get new clips but A pillars would be difficult. There is also a plastic clip at the bottom that can be removed with a forked trim pry tool. Hope this helps. I’m taking my 94 LWB apart now for paint and a new interior.
