DS Window Trim can't put back in

[NovaFZJ80]

Installed new speaker in the DS door panel...easy taking apart the door panel, but still can't get the window trim back in between the glass and panel...how the heck do you angle the trim to get it back into the slits that hold the trim in place....tried a few times, but not all would go into the slits and hold the trim snug...trim closer to the side mirror was easy, but the rest would go between the glass and the door panel.. figure have to resolve this before moving on to the PS door
