Barracuda should be the same.

The pad has spring steel tabs that snap in.
( The ABC pads look nice but I have not had good luck snapping them in. The spring steel is too brittle)

I recall someone saying that the aftermarket arm rests require screwing the pads on before installing the armrest plastic to the body.
