Gary,
The trim snaps onto long metal strips. The strips are held in place with a special metal piece that slides onto the pins that are welded to the car.
There are also a few fasteners and screws used as well in certain areas. It's been a long time since I removed a set, memory may be a little foggy.
I may have a set here, would have to look. Big issue is shipping, pieces are long and curved.
