1989 300 SE. I want to remove the B pillar covers so I can re-glue the vinyl where it's coming loose around the upper seat belt slide. I've tried prying on it near the top but I can't seem to get it to pop off. I can get about a 1/2" gap but it doesn't release and I'm afraid to pry any harder for fear I'll break something.

I tried a search, so know lots of members have done this, but couldn't find an answer to how hard I can pry and where I should be appling pressure without hurting anything.

If anyone could provide instruction I'd be grateful. Also, do I need to buy new clips to replace any that might break? If so which ones. Thanks.
