@jethro49er, Terry, Normally they have clips just like the others. I used a V-pry/ long screw driver and a flashlight to locate the clips from behind. Use the screw driver to apply pressure. It keeps the clips from breaking off. The 1st link to manual below may help, 2nd link is the different D piller trim you may be able to see the clips,etc. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
