Elrod90xj

I'm wanting to replace the headliner in my 1990 xj base. I was trying to get the interior trim off but I can't get past the top of the rear window in the cargo area. I took all the trim off around the rear hatch by removing the screws and it just came right off. But when I took the screws out above the rear side windows that trim wont come down. And there are no more screws to take out. I also took off my oh **** handles. Are the trim pieces just held on by clips? If so, is there an easy way to get them out? I pulled on them a little but didnt want to break anything. And the pillars don't have screws either except the a pillars that have those plastic caps covering them. Any ideas, tips, or tricks would be greatly appreciated. Thanks!
